AVONDALE, Ariz. -- (AP) -- Joe Gibbs says he never considered firing Kyle Busch over the drivers' road rage incident in the Truck Series race at Texas.
But Gibbs says Busch will face more punishment from the race team, including financial penalties.
Busch will run Sunday's race at Phoenix International Raceway without primary sponsor M&M's. The company did want to sponsor Busch for the final two races of the season, so Joe Gibbs Racing longtime partner Interstate Batteries will be on the car.
Busch was suspended by NASCAR last weekend for intentionally wrecking Ron Hornaday Jr. under caution early in the truck race at Texas. He also was fined $50,000 and placed on probation through the end of the year.
