Kyle Busch expected to be the center of attention at Bristol Motor Speedway, where he's won four of the last five Sprint Cup races.

But with him losing his driver's license Tuesday as punishment for his 128 mph speeding ticket back in May. Then came an on-track incident in Wednesday night's Truck Series race that has once again put him at odds with Kevin Harvick.

Busch tangled on track in the Trucks race with Elliott Sadler, who drives for Harvick in the Nationwide Series. After contact between the two sent Busch into the wall, Busch intentionally wrecked Sadler a few minutes later as retaliation.

Busch later indicated the incident stemmed from his long-running problems with Harvick.
