Kyle Busch didn't run in the Nationwide Series or Sprint Cup races on Saturday or Sunday at Texas Motor Speedway because of his actions during the truck race on Friday night.
NASCAR handed down additional penalties to Busch on Monday, including a $50,000 fine and placing him on NASCAR probation until the end of the year.
On Friday night, Busch intentionally wrecked Ron Hornaday under caution of the NASCAR Camping World Truck Series WinStar World Casino 350k. Hornaday entered the race in championship contention, but Busch put an end to those.
NASCAR parked Busch for the remainer of the truck race, and then parked him for the weekend's races, as well.
NASCAR released a statement saying Busch violated Section 12-1 (actions detrimental to stock car racing) of the 2011 NASCAR Rule Book.
In issuing Monday's penalty, NASCAR went on to say that "if during the remaining NASCAR events in 2011 there is another action by the competitor that is deemed by NASCAR officials as detrimental to stock car racing or to NASCAR, or is disruptive to the orderly conduct of an event, the competitor will be suspended indefinitely from NASCAR."
