Driver Tony Stewart has pulled out of this Sunday's NASCAR Sprint Race, the Stewart-Haas Racing organization has said.

Driver Jeff Burton will take his place at this weekend's Michigan International Speedway in Brooklyn. The group was careful to note that while this is Stewart's second cancellation, his plants for "upcoming Sprint Cup races have yet to be determined."

Earlier on Thursday, Kevin Ward Jr., who was killed after being struck by Stewart's car last week at a racetrack last week, was laid to rest near his hometown of Turin, New York. No charges have been filed against Stewart yet although an investigation is continuing.
