CHARLOTTE, N.C. (AP) — First, Kevin Harvick embarrassed the field with a dominating victory at Dover.

Then his victory celebration made some of his competitors wonder if the reigning Sprint Cup champion had something to hide.

Many believe Harvick backed his car into the wall during his celebratory burnout, creating damage to his Chevrolet. Harvick on Tuesday denied any knowledge of hitting the wall, but some wondered if the action was done to limit NASCAR's ability to inspect the car after the race.

Brad Keselowski said Tuesday it was "absolutely" common for drivers to intentionally damage their cars after a race, and Denny Hamlin called on NASCAR to figure out a way to keep cars intact for the technical inspection.
