CHARLOTTE, N.C. -

Tony Stewart says he will not race Sunday at Michigan International Speedway, skipping a second straight NASCAR Sprint Cup race since striking and killing a driver in a dirt-track race at a small New York track.

"Tony Stewart has decided not to compete in the NASCAR Sprint Cup Series event this weekend at Michigan International Speedway in Brooklyn," Stewart-Haas Racing said in a post on Twitter Thursday. "Veteran driver Jeff Burton, a winner of 21 Sprint Cup races, will pilot the No.14 Mobil 1/Bass Pro Shops Chevrolet SS for Stewart-Haas Racing (SHR) in place of Stewart."

Stewart's plans for the future Sprint Cup races has not been determined, his team said.

Stewart also sat out Sunday at Watkins Glen, a day after he struck and killed Kevin Ward Jr. during a sprint car event in Canandaigua, New York. After Stewart clipped Ward's car, sending it spinning, Ward got out of the car during the caution period, walked down the track and was hit by Stewart.

Ward's funeral was Thursday in Boonville, New York.

Stewart's dirt-racing career is on hold, and he could face criminal charges.
