Tony Stewart, Danica Patrick and Jamie McMurray crash in Dover practice

Tony Stewart, Danica Patrick and Jamie McMurray each had to go to a backup car after they were involved in a crash less than four minutes into Sprint Cup practice Friday at Dover International Speedway.

All climbed from their cars. They were evaluated and released from the infield care center.

This marked the first accident Stewart has had since returning to the car. He missed the first eight races of the year after suffering a burst fracture of the L1 vertebra in an ATV accident Jan. 31 in the California sand dunes.

Asked about Stewart’s condition after the accident, Patrick said: “He left the medical center, so he is okay enough for that. Only he knows if he feels really sore or anything like that. I’m sure that anything that jolts his back will probably play some part. Hopefully, if it’s anything it goes away quickly.”

The incident started when Patrick dumped oil and hit the wall in Turn 4. Stewart and McMurray were behind and lost control in the oil. Both hit the Turn 4 wall hard. Both Patrick’s car and Stewart’s car came to rest along the inside frontstretch wall. McMurray stopped his car along the frontstretch.

Greg Zipadelli, competition director at Stewart-Haas Racing, told FS1 that it appeared to be a gear failure on Patrick’s car that caused the incident. He also said that Kurt Busch‘s team had a similar issue but caught it before it got worse.

“There’s obviously a manufacturer problem,” Zipadelli told Motor Racing Network.

Said Patrick: “I got back to the throttle and it was like a really muffled, like it blew an engine and then it just got sideways and hit the wall. As you can see there were lots of flames too, obviously, some kind of oil or something like that in there that created that.

“I really feel bad because Jamie’s elbow hurt pretty bad and I don’t know if Tony (Stewart) is feeling perfect, but definitely unfortunate. Not something we commonly see. Not a lot of things like that happen, I feel like, these days. Definitely, unfortunate for the first couple of laps of practice and the fact that rain is coming. Hopefully, everybody feels okay.”

Patrick said that McMurray had a “big knot” on his left elbow. McMurray later returned on track with his backup car.

All three drivers made it back on track in a backup car before the session ended.

Results, stats for Truck Series’ JACOB Companies 200 at Dover

With his victory in the JACOB Companies 200 at Dover International Speedway, Matt Crafton became the fifth different winner through the series’ first five races of the year.

Crafton led the last 78 laps, outrunning Daniel Suarez to the win.

Filling out the top five was Christopher Bell, Johnny Sauter and Cole Custer.

Dover win gives Matt Crafton lead in Truck point standings

Winning the Camping World Truck Series’ race at Dover International Speedway launched Matt Crafton five spots to the top of the point standings.

Crafton leads Timothy Peters by two points after five races this season.

Filling out the top five is Daniel Hemric, Ryan Truex and Spencer Gallagher.

Matt Crafton takes first win of year in first Dover victory

With a Daniel Suarez behind him and hungry for his first-career win, Matt Crafton stayed perfect in the final 78 laps of the JACOB Companies 200 to win his first Camping World Truck Series race of 2016.

Crafton, a two-time series champion, hadn’t won at Dover International Speedway in his first 15 starts at the 1-mile track. Now Crafton is eligible for the Truck series’ Chase playoff.

“I always wanted Miles (Dover’s trophy),” Crafton told Fox Sports 1. “We’ve came close and ran second (in 2013). This Menards Toyota Tundra was fast today. It’s all about these guys behind me, I can’t say enough about them – they never give up because we were not very good in the last practice.”

Crafton started fifth after Friday’s qualifying session was rained out.

“Last night (crew chief) Junior (Joiner) sat down and they worked on it all day and made a little headway and finally made progress,” said Crafton, who took the lead on Lap 123. His closest challenger was Suarez, who wasn’t able to get close enough to Crafton’s rear-bumper during the last 27 lap green-flag run.

“I was trying to run the wheels off this thing to try and complete the pass,” Suarez told Fox Sports 1. “We were a little faster than (Crafton) but clean air is a big difference here.”

Suarez’ runner-up result was his best finish in four Truck starts this season. He had failed to finish in the top 15 in his first three races.

HOW MATT CRAFTON WON: After taking the lead on Lap 123, Crafton held off all challengers through two restarts to lead the final 78 laps.

WHO HAD A GOOD RACE: Daniel Suarez was in the top five all afternoon, but couldn’t catch Crafton in the final stretch, finishing second for the fourth time in his Truck career … A week after crashing on the last lap at Kansas, Johnny Sauter kept his truck out of trouble, finishing fourth for his second top five of the year … Cole Custer bounced back from a penalty for jumping a restart to finish fifth, his best finish of the year.

WHO HAD A BAD RACE: Pole-sitter William Byron led the first 80 laps, but lost the lead during pit stops. The rookie pit under caution with 30 to go and was penalized for his crew going over the wall too soon before finishing 11th … ThorSport teammates Ben Rhodes and Rico Abreu were in the top 10 on a Lap 61 restart when Rhodes got loose in Turn 3 and made contact with Abreu, sending them both into the wall. It was the second accident in as many races for both drivers… With 69 laps left and right after making a green-flag stop, John Wes Townley got loose in Turn 3, overcorrected and hit the outside wall in Turn 4. Townley finished 29th.

NOTABLE: All five races this season have been won by a different driver, four of them by series regulars.

QUOTE OF THE DAY: “I’ve been telling Junior (Joiner) all year, to get out of the box and he said we have to win a race first. Now we can get out of the box.” – Matt Crafton after his first win of 2016.

NEXT: N.C. Education Lottery 200 at Charlotte Motor Speedway; May 20 at 8:30 p.m. ET on Fox Sports 1.

M&M'S REVEALS KYLE BUSCH'S NEW ALL-STAR RACE NUMBER

The M&M's Racing with Kyle Busch Facebook page showed off a special Sprint All-Star Race paint scheme that honors the driver's partnership with Mars, Inc., complete with a number switch to celebrate the company's 75th anniversary.

Busch will drive the No. 75 M&M's Toyota next Saturday in the Sprint All-Star Race to celebrate the diamond anniversary. M&M's, Snickers, Double Mint and Pedigree, all of which have been part of the No. 18 car's livery since the partnership formed in 2008, are all Mars, Inc. brands. It's a one-race switch only.

"NASCAR fans have been enthusiastic all season about the M&M's 75th Anniversary, so we're excited to continue the celebration by changing Kyle's race car from the No. 18 to No. 75," Tanya Berman, director, M&M's Brand said in a company release. "It has been an amazing 75 years for the M&M's brand and this year not only allows us look back at our accomplishments, but forward as well to our exciting future."

"We've had fun all season celebrating M&M's birthday with our fans -- there has been a lot to celebrate since their big year comes right after our incredible championship," Kyle Busch said in the release. "For us the best part has been reading our fans' favorite M&M's racing memories, and hopefully with our success so far this season, we've been able to make a few more."

The defending Sprint Cup Series champion, Busch already has three wins in the first 11 races of the 2016 season, including victories at Martinsville, Texas and Kansas. Last week was Busch's first win at Kansas, and he gets another chance to check off another track next week -- Charlotte.

Busch has yet to win at Pocono or Charlotte Motor Speedway, site of the May 29 Coca-Cola 600 (1 p.m. ET, FOX, PRN, SiriusXM NASCAR Radio.)

Haas F1’s Romain Grosjean targets Sonoma for possible NASCAR debut

Haas Formula 1 driver Romain Grosjean believes the best chance of making his NASCAR debut will come at Sonoma in late June.

Grosjean expressed an interest in trying out NASCAR after joining Stewart-Haas co-owner Gene Haas’ new Formula 1 operation for its debut season in 2016.

The Frenchman confirmed to NBC Sports in February that he had discussed the possibility with Haas and restated his desire when speaking ahead of this weekend’s Spanish Grand Prix in Barcelona. Grosjean admits he still needs permission.

“So far I haven’t spoken with my wife!” Grosjean said.

“Definitely I want to do it. I think it’s something we’ve discussed since day one. It would be great experience. When it’s going to happen, I don’t know. It’s 21 races, it’s quite a tight schedule already in Formula 1. Of course, you don’t want to start on an oval, I wouldn’t feel very comfortable.”

Grosjean’s best opportunities for a road course appearance come with the Toyota/Save Mart 350 at Sonoma on June 26 and the Cheez-It 355 at Watkins Glen on August 7. However, the race at The Glen would cut into F1’s three-week summer break.

“That’s a problem,” Grosjean said. “Sonoma is better, I think.”

Sonoma may be better for Grosjean, but it would create a brutal five-weekend run of racing that involves a great deal of travel.

After the Canadian Grand Prix on June 12, Grosjean will venture to Azerbaijan for the nation’s first F1 race on June 19 before potentially heading to California to make his NASCAR debut.

Following Sonoma, Grosjean would then need to go straight to Austria for the next F1 race on July 3, which is then followed by the British Grand Prix one week later.

A key note is that Stewart-Haas Racing would not be allowed to field an additional car for Grosjean at either event. He would have to drive for another team. The NASCAR Sprint Cup Rule Book permit teams to field four cars only “unless otherwise authorized by NASCAR.” Richard Buck, managing director of the Sprint Cup Series, told ESPN.com’s Bob Pockrass that no team could field a fifth entry for a rookie. A potential opportunity could come with HScott Motorsports, which is aligned with Stewart-Haas Racing and fields two cars for Michael Annett and Clint Bowyer.

Grosjean ruled out racing on ovals in NASCAR and IndyCar, including the Indianapolis 500.

“I love watching the race, but I’ve never been attracted by it, so Le Mans 24 Hours yes, Rally Monte Carlo yes, but ovals… I’d probably miss turning right,” Grosjean said.

Having previously raced in GTs, Grosjean is no stranger to closed cockpit racing. Although he conceded there would be much to learn in NASCAR, it is a challenge he relishes.

“It’s probably a bit heavier and more powerful,” Grosjean said of Cup cars. “The brakes don’t look to be the best brakes in the world. There’s a lot of contact as well. A few things to learn, but why not? It would be fun.”
