The executive vice president of Stewart-Haas Racing says Tony Stewart is grieving - and it will be up to the star driver to decide when he's ready to get back in the car.
Jeff Burton will drive the No. 14 car in Stewart's place in Sunday's NASCAR Sprint Cup race at Michigan International Speedway.
SHR executive VP Brett Frood says they haven't discussed any other races.
Stewart is skipping a second straight Cup race since striking and killing driver Kevin Ward Jr. at a dirt-track race in New York last weekend.
Frood did not say where Stewart was Friday, but he said Stewart was surrounded by his closest friends and family.
Frood says it was Stewart's decision to skip this weekend's race.
