The start of the NASCAR Cup Series race at Michigan International Speedway was delayed by inclement weather on Sunday afternoon.
The FireKeepers Casino 400 (USA Network, NBC Sports App, MRN, SiriusXM NASCAR Radio) was scheduled to take the green flag at 3:01 p.m. ET before rain doused the 2-mile, D-shaped oval in Brooklyn, Michigan. NASCAR began pre-race ceremonies 4:05 p.m. ET and fired the engines. If weather interferes again and the event cannot be completed Sunday, the race would be official at the completion of Lap 100, signifying the halfway mark in the 200-lap event.
