Since being diagnosed with a concussion following the Oct. 7 race at Talladega, Ala., Earnhardt has participated in a rehabilitation program directed by Charlotte neurosurgeon Dr. Jerry Petty. Throughout the process, Petty consulted with Dr. Micky Collins, director of the University of Pittsburgh Medical Center Sports Medicine Concussion Program.
“Dale Jr. has done everything asked of him,” Petty said. “He hasn’t had a headache since Oct. 12, and we have not been able to provoke any symptoms since that time. I have informed NASCAR and Hendrick Motorsports that he is medically cleared for all NASCAR-related activity.”
