NASCAR driver Kurt Busch and his team have had a tough week.
The Sacramento Bee reports that Busch's crew chief, Steve Addington, will not return to the team in 2012. Addington had been part of Busch's team since 2010.
"Steve Addington is no longer with our organization," Penske Racing president Tim Cindric tweeted. "We appreciate the successes we experienced together and wish him well in his future endeavors."
Some are speculating that Addington will join Stewart-Haas Racing as crew chief for Tony Stewart. Stewart won the Sprint Cup title on Sunday. Busch placed 11th in points for the season.
Addington's departure comes days after Busch used abusive language towards members of the media after pulling into the garage during Sunday's race for repairs. Busch later released a statement apologizing for his behavior.
"Unfortunately, our result in the season-ending race at Homestead on Sunday was not what we had hoped for as a team. In my frustration with the loss of my transmission early in the race, I let my emotions get the better of me. I regret having done this and apologize to the sponsors of Penske Racing , to NASCAR, its fans, to the media and in particular, Dr. Jerry Punch," Busch said.
