Bobby Labonte and Ricky Rudd were also involved. All 4 cars were out of the race. The racer estates on lap 20 and Kurt Busch had the lead, only for Biffle took it again soon afterwards.

Sterling Marlin stayed out to lead a lap but at the restart, Newman was led over by Travis Kvapil and Greg Biffle in 2nd and 3rd positions respectively. Shortly after the restart, a crash occurred on lap 65, when Matt Kenseth nudged the back of Elliott Sadler's car; this would bring out the 3rd caution. Carl Edwards and Tony Stewart were also involved, though the latter's car only received minor damage.

The race restarted came on lap 70 with Newman taking the lead, having Kvapil, Jimmie Johnson, and Biffle behind him. On lap 77, Kenseth went a lap behind after a tire went down as a result of his crash with Sadler earlier.

Lap 86 brought out the 4th caution when Jason Leffler, trying to get onto pit road, got pushed by Ken Schrader. Most drivers pitted, with Kasey Kahne ending up in the lead from Newman and Kvapil. Ku.

Newman and Johnson battled for the lead at the restart. With 44 to go, Hermie Sadler crashed into the inside wall bringing out another caution with Johnson leading over Gordon. The battle resumed with 39 laps left. Newman got into the back of Gordon with 34 laps to go, which caused them to lose 3 positions.
