While testing at Road Atlanta in August, Keselowski was driving over 200 miles per hour on a straightaway, but his brakes unexpectedly failed. Keselowski could not stop and slammed into a solid concrete wall violently at approximately 190 MPH and broke his left ankle. Keselowski was airlifted to a hospital, claiming he had terrible back pain. Despite racing with injuries, Keselowski won his second race of the season at the Good Sam RV Insurance 500 at Pocono Raceway less than a week after the accident. The win put him into contention to grab one of the two "Wild Card" spots available in the Chase for the Sprint Cup championship.
