RICHMOND, Va. (AP) - Kurt Busch says his crew chief is leaving at the end of the season
Busch said Friday that Pat Tryson informed him about his decision this week.
Tryson has refused to discuss his 2010 plans, but it's believed he's going to Michael Waltrip Racing to be crew chief for Martin Truex Jr.
Busch said the timing of his decision is not ideal. The Chase for the championship begins next week in New Hampshire, and barring a disaster Saturday night at Richmond International Raceway, Busch will be in the 12-driver field.
