Dale Earnhardt Jr. was cleared to return to the track this weekend at Martinsville Speedway after missing the past two races with concussion symptoms.
ESPN.com reported that Earnhardt ran a 123-leap test Monday in Georgia and was examined Tuesday by Dr. Jerry Petty, a neurosurgeon in Charlotte, N.C.
"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."
Earnhardt sought medical counsel after he crashed two weeks ago at Talladega and said he had a lingering headache. Earnhardt also reported having similar pain after an Aug. 29 test crash at Kansas.
Missing the past two races essentially ended Earnhardt's Sprint Cup championship hopes. Regan Smith filled for Earnhardt and finished 38th at Charlotte and seventh at Kansas.
