CHARLOTTE, N.C. (AP) -- NASCAR has fined team owner Richard Childress $150,000 and placed him on probation through the end of the year for his altercation with driver Kyle Busch.
Childress approached Busch following Saturday's Trucks race at Kansas Speedway and apparently punched him several times. The car owner was upset that Busch had bumped into Joey Coulter on the cool-down lap after the race.
NASCAR said before Sunday's race that Busch was not at fault.
Childress was allowed to stay for the race, but his access at the track was restricted to specific areas.
