Tony Stewart has decided not to race this weekend at Michigan. The driver was involved in an accident that killed fellow driver Kevin Ward, Jr. last Saturday night.

His team released the following statement Thursday afternoon:

"Tony Stewart has decided not to compete in the NASCAR Sprint Cup Series event this weekend at Michigan International Speedway in Brooklyn.

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.

This driver change pertains only to Michigan. Stewart's plans for upcoming Sprint Cup races have yet to be determined."

There will be a press conference at Michigan International Speedway on Friday at 9 am Central Time.

Burton has been running a limited schedule for Michael Waltrip Racing this season. He has driven in 2 races this season, the last of which was New Hampshire.
