CONCORD, N.C. (AP) - Dale Earnhardt Jr. knew he had suffered a concussion in an August crash so jolting that other drivers tweeted about it immediately after the impact.
So he kept it a secret until a 25-car accident on the last lap Sunday at Talladega left him with a lingering headache.
NASCAR’s most popular driver sought medical attention from a neurosurgeon, who found Earnhardt had indeed suffered two concussions in six weeks and could not be medically cleared to race. Earnhardt said Thursday he will sit out the next two weeks, at Charlotte and Kansas, ending his championship chances.
“I would love to race this weekend, and I feel perfectly normal and feel like I could compete if I were allowed to compete,” Earnhardt said. “But I think that the basis of this whole deal is that I’ve had two concussions in the last (six) weeks, and you can’t layer concussions. It gets extremely dangerous.”
A decade ago, it was Earnhardt who helped spur changes in how NASCAR handled drivers showing signs of a concussion.
He self-diagnosed a concussion from an accident at California, but didn’t tell anyone about it until revealing in an interview weeks later that he’d been having difficulty focusing and communicating with his crew chief. Within days of his admission, NASCAR strengthened its commitment to keeping drivers with concussions off the track.
NASCAR ruled that drivers unable to drive their car back to the garage after an accident had to make a mandatory trip to the infield care center. The attending physician could then refer a driver to a neurosurgeon for a CT scan or MRI if they suspected a concussion.
Clearance to race after suffering a concussion is not given until after a driver obtains a medical release.
“I think we’ve got a pretty good history of sending drivers to the care center and then also to a neurologist if we think there may be any cause to do so,” said NASCAR senior vice president Steve O'Donnell, who added that only nine drivers from NASCAR’s three national series have suffered concussions in the last five years.
Of course, Earnhardt proved Thursday that NASCAR isn’t always in the know.
Earnhardt’s first concussion this season came in an Aug. 29 wreck during a tire test at Kansas. His crash into the wall when his right front tire failed was so hard that Brad Keselowski immediately tweeted about. Earnhardt was seen after the accident in the back of an ambulance, but was not treated in the infield care center and did not seek further examination elsewhere.
He attended a Washington Redskins exhibition game later that night, but admitted Thursday he knew he suffered a concussion.
“You know your body, and you know how your mind works, and I knew something was just not quite right,” he said. “But I decided to just try to push through and work through it. I’d had concussions before and knew exactly kind of what I was dealing with.”
Kansas Speedway president Pat Warren said Thursday the speedway was well-staffed with medical personnel for the August tire test, and that Earnhardt was assessed in the ambulance by a paramedic who has worked for 12 years at the track.
