Matt Kenseth and Tony Stewart brought out the caution flag after wrecking each other on lap 332 of tonight's Sprint Cup race at Bristol. Stewart passed race leader Kenseth on a restart, only to have Kenseth drive in under Stewart. Racing side by side, Kenseth in the low groove and Stewart up high, Stewart was intent on keeping the race lead. Kenseth slid up the race track into Stewart, causing contact between both cars and eventually causing them spin out and hit the inside wall near Turn 1.
The crash clearly upset Stewart, so much so that he waited on pit road for Kenseth to pass by. As Kenseth's car approached, Stewart hurled his race helmet at Kenseth's race car, striking it just above the front grill. Stewart raised his hands to the cheering Bristol crowd and boarded the awaiting ambulance for the mandatory ride to the the infield car center.
After being released from the infield care center, Stewart said in an interview
“I checked up twice to not run over him and I learned my lesson there—I’m going to run over him every him every chance I’ve got from now until the end of the year, every chance I’ve got."
Denny Hamlin went on to win the race for Joe Gibbs Racing. Kenseth and Stewart finished 25th and 27th respectively.
