CHARLOTTE, N.C. (AP) - Casey Mears will fill in for Brian Vickers during Saturday's Sprint Cup All-Star race at Charlotte Motor Speedway.
Red Bull Racing says Mears will drive the Number 83 Toyota for Vickers, who is undergoing treatment for blood clots in his legs and near his lungs. Mears finished 22nd while subbing for Vickers last weekend at Dover.
NASCAR granted Red Bull's request to switch drivers for the race.
Red Bull said Tuesday that Vickers has responded well to treatment but has not issued a timetable for when the 26-year-old can return to racing.
