Ricky Stenhouse Jr. was fined $75,000 by NASCAR on Wednesday for fighting with Kyle Busch after the All-Star race at North Wilkesboro Speedway.

Stenhouse’s father, who joined the fracas, was suspended indefinitely. Busch was not penalized for his actions in the Sunday night race.

The two tangled on the first lap and then Busch seemed to deliberately wreck Stenhouse on the second lap. Stenhouse parked his damaged Chevrolet in Busch’s pit stall, where it had to be towed away by NASCAR.

NASCAR on Wednesday also suspended Stenhouse mechanic Clint Myrick for eight races and engine tuner Keith Matthews for four races.

Stenhouse in the fight vowed to wreck Busch this Sunday during the Coca-Cola 600, to which Busch replied, “Bring it.”

Busch’s car owner isn’t taking the threat lightly. Richard Childress vowed to fight Stenhouse himself if he goes near Busch’s car at Charlotte Motor Speedway
