CHARLOTTE, N.C. (AP) — Tony Stewart has been cleared to return to racing and will be back in his car Friday at Richmond International Raceway.
The three-time NASCAR champion missed the first eight races of the season with a fractured vertebra suffered in a January all-terrain vehicle accident.
The injury occurred one week before Stewart was scheduled to start his final season in NASCAR. He's retiring at the end of this year.
