Kevin Harvick, Greg Biffle clash

MARTINSVILLE, Va. -- Kevin Harvick and Greg Biffle had a run-in on the track when the Sprint Cup Series got in its only practice after the rain stopped Saturday, and then had words as the confrontation spilled over into the garage later.

On the track, Biffle ran into the back of Harvick's car. Harvick, who is fifth in the series standings 26 points behind leader Carl Edwards, later hit Biffle in the back.

The drivers later stopped at the exit of Turn 2, then headed for the garage, where Harvick pulled in alongside Biffle, then pulled ahead, momentarily blocking Biffle's access to his stall. Biffle turned in anyway, clipping the back of Harvick's car.

After climbing from his car, Biffle headed to Harvick's garage stall, drawing a crowd of team members and officials, even though the conversation appeared to become amicable.

Biffle's teammates, Edwards and Matt Kenseth, are 1-2 in the point standings.
