NASCAR fined Kyle Busch $50,000 and placed him on probation for the remainder of the calendar year for intentionally wrecking Ron Hornaday Jr. in last Friday's Camping World Truck Series race at Texas Motor Speedway.
The sanctioning body took initial action against Busch on Saturday by suspending him from the Nationwide and Sprint Cup Series races at Texas.
In issuing Monday's penalty against Busch, NASCAR said in a statement 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."
NASCAR also noted that the parking directive has been lifted, which will allow Busch to participate in next Sunday's Sprint Cup race at Phoenix International Raceway. Busch is not on the preliminary entry list for Saturday's Nationwide event at Phoenix.
Busch fell from seventh to 11th in the Chase for the Sprint Cup point standings, as he became one of three drivers to be mathematically eliminated from championship contention. He is now 100 points behind leader Carl Edwards.
