The green flag for Sunday's race was scheduled for 3:24 p.m. ET but as of 3 p.m., storms with heavy rain and lightning covered the speedway. Up to 5,000 fans were allowed to attend Sunday's race and had to be cleared from the grandstands.
Should the race be postponed, it will be rescheduled for 3 p.m. ET Monday and broadcast live on Fox Sports.
