Race day is finally here and the 22nd running of the Crown Royal presents the Jeff Kyle 400 at The Brickyard is set to kick off Sunday at Indianapolis Motor Speedway. The Sprint Cup Series teams have been thrown for a loop this weekend, as NASCAR has introduced a new high-drag rules package this weekend.

Teams spent all of Friday practicing the new package, but mostly in single-car runs. With few teams racing together during Friday's session, there are a host of unknowns heading into Sunday's race.

This also marks veteran Jeff Gordon's final Brickyard 400 start. The winner of the inaugural NASCAR race at IMS in 1994 is the defending race winner, has a total of five victories, but will start Sunday's race from the 19th starting spot.
