Team owner Richard Childress is facing punishment by NASCAR for a physical altercation with Kyle Busch on Saturday afternoon at Kansas Speedway.
The sanctioning body summoned both Childress and Busch on Sunday morning – with Busch's team boss Joe Gibbs also attending – following reports that stated that the 65-year-old team owner had attacked Busch physically in the garage area.
The incident came after the Joe Gibbs Racing driver had contact with RCR's Joey Coulter during the cool-down lap of Saturday's Truck Series race, where they had battled hard for fifth place in the closing laps.
NASCAR president Mike Helton addressed the media on Sunday morning at Kansas and warned that action will be taken against Childress for his behaviour. He also stated that Busch, who is currently serving a probation period following a post-race incident at Darlington with RCR's Kevin Harvick, did not do anything to provoke Childress' attack in NASCAR's opinion, and neither did he go beyond the limits of what his probation status allows.
"NASCAR has reviewed the incident involving Richard Childress and Kyle Busch after the NASCAR Camping World Truck Series race Saturday at Kansas Speedway," the sanctioning body said in a statement. "We have met with all parties involved and have determined what happened yesterday is unacceptable and will not be tolerated by NASCAR.
"Richard Childress's actions were not appropriate and fell far short of the standard we expect of owners in this sport. We have met with Childress this morning and made our position very clear to him. Further, we expect he will make it clear to all in his organization to ensure this situation does not escalate any further. We will announce our actions regarding this incident Monday.
"Kyle Busch remains on probation with NASCAR and we continue to watch his actions carefully. However, we have determined that Kyle's involvement in this incident does not violate his probation and no further action is required."
Although Childress will be at the track for Sunday's Sprint Cup Series race at Kansas, Helton stated that limitations were being set on where he was allowed to be at the circuit.
Kyle Busch, who was competing for his own squad in Saturday's Truck race, will start Sunday's Cup race from the second row of the grid, driving the No. 18 Joe Gibbs Racing Toyota.
