One lap to go at Daytona and Kyle has the lead from Tony Stewart. Coming out of the final turn to the finish, Stewart gets Busch a bit loose and swings around to the outside. Busch tries to come up to block but Stewart was already too far, so Tony ends up clipping Kyle's rear quarter panel and sends him spinning out into the wall. That started a chain reaction that sent a couple more cars into Busch, and several more into each other.
Busch's car was crushed from several angles, but he got out and walked away.
Stewart won the race, with Jimmy Johnson a very close second.
All in all, a great and exciting finish.
