PHOENIX (AP) — A 14-year-old boy bolted off his school bus and ran to rescue his dog after seeing his Phoenix family’s home was on fire, authorities said.

Fire Capt. Aaron Ernsberger said the boy had just gotten on the school bus at a nearby stop Friday morning. As the bus drove by his home, the boy saw smoke coming from the house and got off the bus, Ernsberger said.

The boy went to the front door and opened it but could not enter because of smoke, flames and heat. He then ran to the back door and let the family’s 9-year-old pit bull out, Ernsberger said.

“He was smart enough to not go inside, thank God,” Ernsberger said. Otherwise, “he would not be with us today.”

News video showed smoke billowing from the home and firefighters on its roof where they cut a hole to let out smoke and heat.

No injuries were reported.

The home sustained major smoke and fire damage, Ernsberger said. “All of their belongings are a total loss.”

The cause of the fire wasn’t immediately known.

Officials previously said the boy was 16.

This story has been corrected to reflect that the Fire Department later said the boy’s age was 14, not 16.

Formula One champion Nico Rosberg stunningly retired from racing on Friday, five days after earning his first world championship.

“I have decided to end my Formula One career. I had a very, very clear dream, that was to become Formula One world champion. I have achieved this childhood dream now and I am not willing to do that sort of commitment again,” Rosberg said in Vienna.

“So I have decided to follow my heart, and my heart has told me just to stop there, to call it a day.”

Rosberg said he made the decision on Monday, a day after finishing second at the season-ending Abu Dhabi Grand Prix to clinch the F1 title.

“I am on the peak, so this feels right,” he said.

He wrote on Facebook of the difficulties he faced over a season that took a toll on people close to him: “It was a whole family effort of sacrifice, putting everything behind our target.”

Rosberg had a strained relationship with Mercedes teammate Lewis Hamilton. They came up through the karting circuits to became fierce rivals in F1, constantly needling each other in the media. They dueled for the F1 championship for the last three years. Rosberg was runner-up to Hamilton in 2014 and 2015, but hung on this year to relieve Hamilton of the title in the final race.

Rosberg’s father, Keke, the 1982 F1 champion, said after watching his son in Abu Dhabi that the strain of fighting Hamilton was sapping him.

“I don’t know how much it’s taken out of him,” Keke Rosberg said on Sunday. “Maybe he retires tomorrow.”

All observers thought that was a quip. Mercedes said on its website that 31-year-old Nico Rosberg “will stop racing in Formula One with immediate effect.”

Rosberg said it had been his dream, “my ‘one thing’ to become Formula One world champion. Through the hard work, the pain, the sacrifices, this has been my target. And now I’ve made it. I have climbed my mountain.”

In an online video, the German said: “I’m not willing to do it again next year.”

Rosberg won 23 races (tied for 12th all-time) and 30 pole positions (8th) from 206 races since his debut in 2006.

He began thinking of retirement after winning in Suzuka in early October, “when the destiny of the title was in my own hands.”

Mercedes chief Toto Wolff paid tribute to Rosberg for making a “brave decision.”

“He has chosen to leave at the pinnacle of his career, as world champion, having achieved his childhood dream,” Wolff said. “The clarity of his judgment meant I accepted his decision straight away when he told me.”

PROVIDENCE, R.I. (AP) — Police say a Rhode Island man who streamed himself on Facebook Live driving 114 mph before crashing into a garbage truck and a concrete barrier was driving with a suspended license.

State police say 20-year-old Onasi Olio-Rojas, of Pawtucket, lost control Wednesday on U.S. Route 6 in Providence.

The video posted on Olio-Rojas’ Facebook page shows him driving 114 mph and weaving through traffic. Police confirmed its authenticity.

Rescue crews extricated him from the car after the crash. He was hospitalized in critical condition. Rhode Island Hospital says he was in fair condition as of late Thursday night.

The truck driver wasn’t hurt.

Police say Olio-Rojas had been involved in two prior accidents and has several previous traffic violations. WJAR-TV reports police plan to bring misdemeanor charges against him.

MINNEAPOLIS (AP) — Dez Bryant sashayed through the Dallas locker room with an unmistakable swagger and had nothing but good things to say about his adversary this time around.

It was a stark change from a week ago, when he sparred with Washington cornerback Josh Norman on Thanksgiving. The trash talking Dez and the polite Dez share one thing in common: they both win.

Bryant caught four passes for 84 yards and the go-ahead touchdown in the fourth quarter, helping the Cowboys win their 11th straight game with a 17-15 victory over the Minnesota Vikings on Thursday night.

In a hard-fought battle with cornerback Xavier Rhodes, Bryant’s 56-yard catch set up Ezekiel Elliott’s 1-yard TD in the first half. Bryant caught an 8-yard scoring pass in the fourth quarter after a fumbled punt by Minnesota’s Adam Thielen.

“I knew coming into this game it was going to be a tough match and I had to be on my ‘A’ game,” Bryant said. “Because if I wasn’t, he can get the best of you. We had a good battle. We shared our thoughts throughout the game. It was good thoughts. It’s nice playing games like that.”

Elliott rushed for 86 yards on 20 carries for the Cowboys (11-1). They have the longest single-season winning streak in franchise history.

Sam Bradford threw a 3-yard touchdown pass to Jerick McKinnon with 25 seconds to play, but the 2-point conversion pass failed. Bradford argued for a penalty after he was hit in the face by a defender, but there was no call for the Vikings (6-6). Minnesota played without coach Mike Zimmer after he had emergency eye surgery Wednesday night.

“I’m sick and tired of the reffing in this league right now,” Vikings defensive end Brian Robison said. “I’m sick and tired of it. You’ve got holding calls all over the place that people don’t want to call. Bradford gets hit in the face at the end of the game and you don’t call it. I’m not laying this loss on reffing, but at some point it’s got to get better.”

Bradford completed 32 of 45 passes for 247 yards, Danielle Hunter had two sacks and Kai Forbath kicked three field goals for Minnesota, which has last six of the last seven games after a 5-0 start.

Vikings special teams coordinator Mike Priefer was elevated to head coach for the game and it remains unclear how long Zimmer will be out. Minnesota’s third-ranked defense did their fiery leader proud, holding the explosive Cowboys offense to season lows in points, yards (264) and first downs (13).

“It’s not the best game we played, but we showed up when we needed to and made the plays at the end,” Elliott said.

KEY PLAY

With Dallas’ offense doing nothing, Kyle Wilber made the play of the game when he punched the ball out of Thielen’s hand, then pulled the ball away as the two rolled to the turf. Officials initially did not catch the fumble, but a heads-up challenge by Jason Garrett got the call overturned and Prescott found Bryant on the next play.

CATCHLESS IN MINNEAPOLIS

Cowboys tight end Jason Witten did not catch a pass, snapping a team-record streak of 130 straight games with a reception dating to 2008.

A TD TO TIE TD

Elliott’s 1-yard plunge in the second quarter gave Dallas a 7-3 lead. It was his 12th touchdown rushing this season, tying him with Tony Dorsett for most by a rookie in Cowboys history.

BRADFORD UNDER SEIGE

Playing behind a patchwork offensive line that included center Nick Easton making his first career start in place of the injured Joe Berger (concussion), Bradford was under pressure all night long from a Cowboys defense that has often struggled in that area this season.

Bradford was sacked three times and had to leave the game on the final drive of the second quarter after taking a helmet from Maliek Collins to his rib cage. After getting some medical attention during halftime, Bradford was able to remain in the game.

“I had to take a deep breath,” he said. “After that they were fine.”

The bad news on the injury front for the Vikings came for safety Harrison Smith, who left the locker room on crutches with a walking boot on his left foot. He has been fighting through an ankle injury over the last several weeks.

ZIMMER TRIBUTE

Before the game, the Vikings played a short video of Zimmer addressing the team during a practice. Zimmer’s primary message: “Do your job.”

That has been a common theme during his three seasons in Minnesota, and the organization likely wanted the players to hear it one more time before taking the field. After the video, a picture of Zimmer was put on the big screen with a “Get Well Soon” message attached.

“They fought to the bitter end, and I know coach Zimmer would’ve been very, very proud of them,” Priefer said.

UP NEXT

Cowboys: Dallas heads to New York on Dec. 11 to face the Giants, the only team to have beaten the Cowboys this season.

Vikings: Minnesota will travel to Jacksonville on Dec. 11 to face the Jaguars, hoping the extra time off will be enough for Zimmer to recover and return to the sideline.

MINNEAPOLIS (AP) — For the first time in his 23-year NFL coaching career, Mike Zimmer wasn’t at the stadium with his team.

When the Minnesota Vikings hosted Dallas on Thursday night, Zimmer was at home resting after emergency surgery to repair a detached retina while special teams coordinator Mike Priefer took over as the interim head coach.

Offensive coordinator Pat Shurmur (Cleveland, 2011-12) and offensive line coach Tony Sparano (Miami, 2008-11) each have prior experience as an NFL head coach, but they remained in their roles to minimize the disruption. Zimmer is the play-caller for the defense, considered one of the savviest in the league, and that duty fell to defensive coordinator George Edwards.

Zimmer visited the team hotel to speak to the players before the game, an emotional address during which he expressed his disappointment in not being able to join them, a message they already knew.

“It was a little bit hard for me, because he’s such a competitor,” said Priefer, his voice cracking slightly. “That’s why I love working for him.”

The Vikings played a video clip of Zimmer encouraging the team during training camp with a get-well-soon message on the scoreboard prior to kickoff. General manager Rick Spielman declined to speculate on whether Zimmer would have to miss multiple games during the recovery, but with the Dec. 11 game at Jacksonville the coach is unlikely to be cleared in time for air travel with his condition.

“We have to see how his eye responds to the surgery,” Spielman said. “I do know how intense coach Zimmer is. Talking with him today and with the doctors, as much as he wants to be out there coaching tonight, it’s in his best interest that we get this taken care of. Coach Zimmer has never missed a game. I know how hard this is on him. I can’t express how hard on him it is that he won’t be able to coach. But we have to look after his health.”

Left untreated, retina damage can lead to permanent vision loss . The retina is a thin layer of tissue at the back of the eye. When it’s detached, the cells are separated from the layer of blood vessels that provide oxygen and nourishment. This was the third procedure the 60-year-old Zimmer has had over the past month.

“As hard-headed as he is and as tough-minded as he is, we had some pretty significant talks one-on-one, heart-to-heart, on what is important in life and what isn’t,” Spielman said. “I think after we met, I expressed to him specifically that potentially going blind in one eye is not worth one game in the NFL.”

Zimmer, who got his start in the NFL as an assistant with the Cowboys in 1994 and spent 13 years with the organization, has yet to face Dallas in the regular season as a head coach . The Vikings and Cowboys played last year in the preseason.

Zimmer first experienced trouble with his right eye a couple of days before the Oct. 31 game at Chicago and scratched the eye inadvertently during that game. That prompted team doctors to send him for further examination, which revealed a torn retina. He had surgery Nov. 1 and another one Nov. 8, which left his eye noticeably red. It had cleared up significantly in recent weeks, though, and Spielman said Zimmer wasn’t expected to need further treatment.

But the coach suddenly complained of vision problems during a walk-through practice with the team Wednesday afternoon, and head athletic trainer Eric Sugarman drove Zimmer to seek medical attention. Spielman said the latest diagnosis was a detached retina.

After first revealing the issue at his Nov. 2 news conference, Zimmer said he’d been watching film with his good eye and using reading glasses to write down notes in preparation for that week’s game. With the Vikings mired in a slump with five losses in the last six games, the hard-nosed Zimmer sure hasn’t appeared to back off his approach in the desire to help the team get back on track and catch up in the NFC playoff chase. Zimmer mentioned recently he’s been arriving at his office even earlier than usual, around 4:15 a.m.

Spielman dismissed the theory that Zimmer’s setback this week was related to pushing too hard after the first two procedures.

Whether the situation was the sudden death of his wife, Vikki, when he was the defensive coordinator for Cincinnati in 2009, the kidney stones he had removed in 2014 or the death of his father, Bill, during the 2015 preseason, Zimmer had never missed a game until now.

“It’s not worth the risk,” Spielman said. “And we’re looking out for the long-term of his health.”

SAN JOSE, Calif. (AP) — Michael Phelps wants to dive into Silicon Valley’s investment opportunities as he tries to make the transition from Olympic swimming star and product pitchman to entrepreneur.

“I would love to get involved, whether it’s in a couple little startups here and there, take a little risk, have some fun and see where it goes,” Phelps said in an interview during a recent visit to San Jose, California, while appearing at Intuit’s QuickBooks software conference.

For now, Phelps isn’t providing any details about what he is going to do, though he says he has been getting advice from venture capitalists and other experienced investors in Silicon Valley startups.

Getting into tech investing would be a new direction for Phelps, whose business experience to date consists mostly of his own line of swimwear and endorsement deals with the likes of Under Armour, Visa and Wheaties.

These and other big brands have paid him an estimated $75 million during his career. That’s far more than the $1.65 million that he received from the U.S. Olympic Committee and Speedo for winning a record 28 medals, including 23 golds, in five Olympics. He’s still promoting products; he is currently doing commercials for computer chipmaker Intel in a campaign that began in October.

Whatever he does next, Phelps isn’t ready to start his own investment fund, like retired Los Angeles Lakers star Kobe Bryant did earlier this year with entrepreneur Jeff Stibel. And if Phelps has ideas for founding a startup of his own, he’s keeping them to himself.

Making the leap from pitchman to businessman won’t be easy, said David Carter, executive director of the University of Southern California’s Marshall Sports Business Institute. “Athletes come and go and many talk a big game, but they don’t follow through,” he said. Phelps “is really going to have commit to learning about business and demonstrate his seriousness about it.”

Other celebrities have ventured into the tech industry in search of riches, with decidedly mixed results.

Notable successes include rapper and record producer Dr. Dre, who was part of the founding team that sold Beats to Apple for $3 billion 2014. Actor Ashton Kutcher co-founded an investment fund in 2010 that made early investments in startups such as the ride-hailing service Uber, the home rental-service Airbnb and the music streaming service Spotify. The fund’s value had soared to $250 million from $30 million, based on a review of its books earlier this year by Forbes magazine.

Among the flops: HJR Capital, a tech-investment firm that collapsed in 2009, a decade after former San Francisco 49er lineman Harris Barton founded it and later enticed ex-teammates Joe Montana and Ronnie Lott to join him. In Rhode Island, former Boston Red Sox pitcher Curt Schilling started a video game company that went bankrupt in 2012.

Phelps is exploring ways to expand his business ventures beyond a line of swimwear and other clothing bearing his “MP” logo. Other products are in the pipeline for next year, though he won’t say what.

“I am getting my feet wet,” Phelps said with a grin. “2017 will be a big year.”
