Following an accident that left him with a concussion, NASCAR driver Dale Earnhardt Jr. was sidelined, but has now been cleared to return to the track after being evaluated by doctors.

Earnhardt was examined by neurosurgeon Jerry Petty a day after he ran 123 laps at half-mile Gresham Motorsports in Jefferson, Georgia.

According to Petty, Earnhardt has done everything that has been asked of him in order to make a speedy return to racing, which will take place this weekend at Martinsville Speedway after he missed the last two weeks.

The driver had complained of a lingering headache after the 25-car accident at Talladega on October 7 and was diagnosed with another concussion, which he isn't a stranger to, also suffering one in an August 29 crash during a tire test at Kansas that went untreated.

Regan Smith drove the No. 88 Chevrolet car in Earnhardt's absence, ending his stellar performances of 461 consecutive starts, which is the fifth longest active streak in Sprint Cup Series.

Smith also recently announced that he has signed with the JR Motorsports team.
