Daytona Beach, FL -- (Sports Network) - NASCAR placed Kurt Busch and Carl Edwards on probation for the next six races of the Sprint Cup Series after the two traded intentional bumps following Saturday's Sharpie 500 at Bristol Motor Speedway in Tennessee.

Busch and Edwards, the top two drivers in the Sprint Cup standings, will be on probation starting at this Sunday's Chevy Rock & Roll 400 in Fontana, California. The probation will also cover races in Richmond, Virginia; Loudon, New Hampshire; Dover, Delaware; Kansas City, Kansas; and Talladega, Alabama.

The altercation on Saturday was set up when Edwards nudged Busch from behind with 31 laps to go. Busch got loose, allowing Edwards to move underneath him for the lead.

At the conclusion of the race, a frustrated Busch retaliated by intentionally bumping Edwards on the cool-down lap. Edwards, however, got the best of the post-race ruckus when he spun Busch around.

While Edwards celebrated in Victory Lane, Busch made a trip to the NASCAR hauler for a discussion with officials.

"He hit me in turn one, which got me a little bit loose," Busch said after the race. "Carl's gonna say he's sorry, he doesn't want to race that way; because he always does, you know, Mr. Ed-like. We'll take it and go on. We'll race him that way in the chase if that's the way he wants to race."

Busch is the current Sprint Cup Series points leader with 3,609. Edwards, with 3,397, trails by 212 points.
