The big one hit in Friday's first practice (Video)
Brad Keselowski made contact with Kyle Busch in turn 2 during the first practice for Sunday's Coke Zero 400. A crash started from there.
Busch collected other cars including Martin Truex Jr., Jamie McMurray, Ryan Newman, Carl Edwards and Greg Biffle. Here's how it happened.
Busch wasn't too happy that Keselowski got away from the crash without being involved heavily. Busch and Keselowski aren't exactly on friendly terms. Remember, Keselowski once called Busch an "ass" at driver intros in Bristol when their rivalry was at its hottest.
Keselowski said the wreck "stinks."
Since the crash happened on Friday and qualifying is on Saturday, drivers going to backup cars will not have to start at the back of the pack. If a driver qualifies the backup car, he or she can keep the starting spot earned.
