inspection began Friday – where Jimmie Johnson's car was found to have some illegal modifications – and practices for qualifying were held on Saturday.

The official qualifying session will take place on Sunday (1:05 p.m. ET, FOX), but it is different than every other qualifying session throughout the year. Sunday's qualifying will only lock in two drivers (the pole and outside pole positions), and several other drivers will qualify based on speed.

On Wednesday, drivers will have their last chance of practice before the Gatorade Duel 150 qualifying races, which take place the following day at 2 p.m. ET. The Duels consist of 150 miles and will determine the starting order for the
