Three drivers hit the wall during the session:

* Less than five minutes into the practice session, Dale Earnhardt Jr. went quickly to the top of the speed chart. The No. 88 slammed into the wall hard and suffered heavy damage on the right side. The team went to a backup car.

Earnhardt claimed the PJ1 substance applied to the high line of the track to enhance grip led to his wreck.

* Brad Keselowski brushed the wall about 45 minutes into practice. While his Ford Fusion incurred some scraping damage, the team decided not to go to a backup car.

Kyle Busch then hit the wall in the closing minutes of the session, but his team decided to fix the damage rather than go to a backup car.

Earlier, Busch came off Turn 4 and sailed onto pit road before coming to a stop, backing up and then taking his car to the garage.

He was called to the NASCAR hauler to speak with officials about the incident and the reason behind it.
