Contested over 367 laps on the 1.366 mile (2.198 km) speedway, it was the tenth race of the 2005 NASCAR Nextel Cup season.

The case was settled in his favor, and NASCAR was forced to give up one of its Darlington dates so that a second race could be held at Texas.

The race was situated on the Saturday of Mother's Day weekend in mid-May, a date that was normally avoided by NASCAR over its history.

With four laps to go, Biffle's Roush Racing teammate Mark Martin spun out (sliding into the apron) trying to pass third-place runner and pole-sitter Kasey Kahne.

Biffle took two tires on his final pit stop, while race leader Ryan Newman and Ken Schrader stayed out.
