ROSSBURG, Ohio -- Kyle Busch says that the $150,000 fine NASCAR levied against Richard Childress is the end of the matter for him.
Childress was fined Monday for assaulting Busch after a NASCAR Trucks race at Kansas Speedway, the latest incident between the driver and Childress' race teams. Busch was in Ohio on Wednesday to participate in Tony Stewart's annual charity race.
"NASCAR decided to make the decisions that they felt were necessary," Busch said before the race at Eldora Speedway. "It's pretty much the end of it. It's not my fight."
Busch, who is fifth in the Sprint Cup points race, has run in seven of eight truck races and has four victories this season.
NASCAR also placed Childress on probation through the end of the year, finding the team owner solely at fault for the incident last Saturday. He apparently approached Busch after the race, placed him in a headlock and punched him several times.
"We feel this action is appropriate and are confident all parties involved understand our position on this matter and will move forward appropriately," NASCAR said in a statement announcing the punishment.
Childress, who dodged a suspension from NASCAR, was upset that Busch had bumped into Joey Coulter on the cool-down lap after the race. Childress said in a statement that he accepts the penalty, but he did not apologize for his actions.
