Harvick, who retired from full-time competition in the Cup Series at the end of last season, was asked by Hendrick Motorsports team owner Rick Hendrick if he would run Larson’s No. 5 Chevrolet in All-Star Race practice on Friday at North Wilkesboro (N.C.) Speedway.
Larson was taking part in Indianapolis 500 practice on Friday but will return to run in the All-Star Race main event on Sunday night.
