Pocono NASCAR Cup Series winner Denny Hamlin and runner-up Kyle Busch were disqualified after a post-race inspection of their cars turned up rules violations.

The Joe Gibbs Racing teammates were both stripped of their results.

"There was some issues discovered that affect aero in the vehicle," NASCAR Cup Series managing director Brad Moran said, referencing the front fascias of the cars.

"There really was no reason why there was some material that was somewhere it shouldn't have been. And that does basically come down to a DQ."
