LONG POND, Pa. (AP) -- NASCAR points leader Tony Stewart has wrecked his car during practice at Pocono Raceway and had to go to a backup car.
Stewart lost control of his No. 14 Chevrolet on a turn toward the end of Saturday's first practice and ripped off the nose of his car.
His Stewart-Haas Racing crew quickly got to work on the backup. Stewart leads the points standings and was the pole sitter at Pocono because rain washed out Friday's qualifying.
Stewart says he has confidence in the backup and was set to try it out at the second practice later in the day.
