How the heat races work
The 36 drivers will be split into nine-car groups for four, 25-lap heat races on Sunday. the top-four finishers from each heat will advance into the main event.
Then, the remaining drivers will be sent to the last-chance qualifiers (LCQ). There will be two LCQs with the top-three finishers advancing from those races.
The 23rd and final starting position in the main event will be reserved for the highest car in 2021 owner points that did not advance on merit. Kyle Larson, Martin Truex Jr., Denny Hamlin and Chase Elliott are the first four drivers in line for that provisional.
13 drivers in total will be eliminated and will not take part in the 150-lap main event that follows.
