Kyle Busch brushed the wall early in his first race at Daytona International Speedway since breaking his right leg and left foot in a crash at the track in February.
Trying to pass Jamie McMurray on lap 17 of the 160-lap race, Busch wiggled and tagged the wall. He lost two laps while his crew worked to repair splitter and body damage on his No. 18 Toyota.
It was a potentially costly setback for Busch, who needs to finish in the top 30 in points to make the Chase for the Sprint Cup championship.
Busch missed the first 11 races this season following his Daytona crash in the Xfinity Series season opener, but NASCAR granted him a waiver that would make him Chase eligible with a victory and a top-30 finish in points.
Busch won last week's race at Sonoma Raceway, but needs to average a 14th-place finish over the next 10 races to join the Chase.
