Kurt Busch ran up front all night, and even led 36 laps.

In what he says was a "free-for-all" finish, the one-time champion now racing for a one-car team wound up ninth Saturday night at Richmond International Raceway. He also was mad at Matt Kenseth for moving him out of the way and had a door-slamming battle with ticked off Tony Stewart on pit road.

And he says he has no idea what the equally hot-headed Stewart was upset about.

Stewart didn't stick around to talk after the race. He climbed from his car, rebuked media that immediately surrounded him seeking comment and walked out of the track to a waiting golf cart.

Busch says the mayhem that came on the two-lap sprint to the finish had to be expected.
