NASCAR also placed Childress on probation through the end of the year, finding the team owner solely at fault for Saturday's incident at Kansas Speedway. Childress, 65, apparently approached Busch after the trucks race, placed him in a headlock and punched him several times.
Childress, who dodged a suspension from NASCAR, was upset that Busch had bumped into Joey Coulter on the cool-down lap after the race.
"First of all, I'm responsible for my actions, plain and simple," Childress said in a statement. "As you know, I am a very principled person and have a passion for what we do at Richard Childress Racing. I believe passionately in defending my race teams and my sponsor partners. In this instance, I let that passion and my emotions get the best of me."
Stewart makes a change: Tony Stewart released Bobby Hutchens as director of competition at Stewart-Haas Racing and promoted Matt Borland to vice president of competition. Stewart has one top-five finish this season.
