Seven other drivers are dropp ing to the rear after having to go to backup cars. All were the result of accidents in their Thursday night Duel races.

Those drivers are William Byron (qualified second), Brad Keselowski (qualified 24th), Cole Custer (qualified 27th), Chase Briscoe (qualified 30th), Ross Chastain (qualified 34th), Anthony Alfredo (qualified 36th), and Kaz Grala (qualified 40th).

Martin Truex Jr. is dropping to the rear because his Joe Gibbs Racing team changed his Toyota’s radiator. Truex qualified 26th.

Erik Jones drops to the rear because of an engine change in his Richard Petty Motorsports No. 43. Jones qualified 31st.

The green flag for the 63rd annual Daytona 500 is 3:05 p.m. ET.
