Denny Hamlin suffered a compression fracture in his lower spine during a last-lap crash while racing for the win against former teammate Joey Logano, and Joe Gibbs Racing gave no indication Monday how long its driver could be sidelined.
"I just want to go home," Hamlin tweeted from a hospital in Southern California. He later posted a photo of himself giving a thumbs-up and appeared to be wearing a back brace
The team said he had what is called an L1 compression fracture; essentially, the first vertebra in the lumbar section of his spine collapsed. Hamlin was expected to be released from the hospital Monday and return to North Carolina to be evaluated by Dr. Jerry Petty of Carolina Neurosurgery and Spine Associates.
NASCAR does not race this weekend, but returns to action April 7 at Martinsville Speedway, where Hamlin has four victories.
Hamlin was airlifted from the Fontana track after a collision with Logano on the penultimate turn sent him nearly head-on into the inside wall. Logano managed to finish third despite wrecking into the outside wall after hitting Hamlin, who spun Logano last week at Bristol and sparked a bitter post-race confrontation.
"He probably shouldn't have done what he did last week, so that's what he gets," Logano said Sunday after the race won by Kyle Busch.
On Monday, Logano's car owner said the driver was unaware of Hamlin's condition when he made the comment during a television interview.
"That's a tough thing, Joey had no idea what the situation was with Denny when he was doing the interview," Roger Penske said. "It's one of those things that came out and taken out of context isn't what he meant. He can't take it back, but people are certainly blowing that up to mean something different than what he knew at the time."
Tony Stewart also got into a post-race shoving match with Logano, who aggressively blocked Stewart on a late restart. Stewart claimed Logano threw a water bottle at him when he approached, but crews separated the two before it turned into a full fight.
Stewart later railed against the 22-year-old Logano in several interviews and accused him of being "nothing but a little rich kid that's never had to work in his life."
Logano was 18 when he broke into NASCAR with Joe Gibbs Racing in 2008 with the nickname "Sliced Bread." He'd risen rapidly through the racing ranks with the financial backing from his father, Tom, who used funds from the family's Connecticut waste management company to help his two children pursue their dreams.
Logano had the means to pursue a racing career, and was in Georgia racing quarter midgets at the age of 6 , but Tom Logano's near-constant presence at the NASCAR races hurt Logano's reputation, and him angrily demanding his son go after Kevin Harvick after a 2010 incident at Pocono only made things worse.
On Monday, Patricia Driscoll, girlfriend of Kurt Busch, referred to Logano as (hash)TrustFundRacer in a series of tweets that accused him of reckless racing with "no less than 5 drivers."
"We were lucky that none of the others were hurt by his actions," Driscoll tweeted.
An agitated Penske thought the criticism of Logano's upbringing was out of line.
"He's a solid young man and his family has supported him in racing as many families of professional athletes do in every sport," Penske said. "Anyone who looks at that as a criticism, to focus on that is just petty."
He also said he supported his driver, who signed last year to join the Penske Racing organization as teammate to defending Sprint Cup Series champion Brad Keselowski.
"Listen, Joey is a great driver and what happened at the end there wasn't anything more than hard racing," Penske said. "I stand behind him and I think he's going to go down as one of the greatest drivers to ever race."
It never developed at JGR, where Logano replaced Stewart in 2009 and was teammates with Busch and Hamlin. Signs of a rift between Hamlin and Logano didn't show publicly until after this year's season-opening Daytona 500, when the two exchanged barbs on Twitter.
Then came an on-track incident at Bristol last week, more exchanges on Twitter, and finally their last-lap battle for the win at Fontana. Although the crash seemed to be a result of hard racing, Logano's lack of empathy immediately after the race gave the impression his contact with Hamlin was intentional.
Hamlin got himself out of the car, but then slumped to the ground beside it before an ambulance arrived. He was eventually airlifted out due to traffic around the track.
The injury is a bit more common in open-wheel racing, which has had three incidents of drivers breaking their backs since 2009.
Will Power broke several vertebrae in his lower back in a 2009 crash during practice at Sonoma and missed that event and the final three races of the season. He couldn't train for two months and wore a back brace for almost four months.
He also suffered a compression fracture of his fourth thoracic vertebrae in the 2011 season finale at Las Vegas but missed no racing as he healed during the offseason.
Justin Wilson fractured his fifth thoracic vertebra in 2011 and missed the last six races of the season. Wilson said he was in a back brace for 10 weeks.
Three-time Indianapolis 500 winner Dario Franchitti fractured the L1 vertebrae in his back in a 2003 motorcycle accident. He needed surgery and was out of a race car for almost nine months. In NASCAR, Sterling Marlin missed the last seven races of the 2002 season with a fractured vertebra in his neck.
