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.

After Sunday's race at Richmond, Stewart will participate in a Goodyear tire test at Indianapolis Motor Speedway. He plans qualify and start his car at Talladega Superspeedway in Alabama, but he will give his seat up after the race begins to Ty Dillon. Stewart says the style of racing at Talladega could lead to an accident that could hurt his comeback.

He plans to return to fulltime racing at Kansas the following week.
