The seeding for the five-race 32-driver tournament will be set based on the best overall finishes for drivers at Michigan International Speedway, Mexico City, and Pocono Raceway.
A win at Michigan International Speedway would ensure that a driver will not be seeded any lower than third for the in-season tournament, which will see pairings of drivers face off head-to-head with the highest finisher in the tournament races advancing to the next round of the tournament.
After the opening four races of the tournament, the 32-driver field will be whittled down to just two drivers, who will battle it out head-to-head in the Brickyard 400, the final race of the tournament.
