Kyle Busch clashes with Ron Hornaday in the Texas Truck raceKyle Busch has been fined and placed on probation by NASCAR adding to his suspension from racing last weekend at Texas.

Busch has been fined $50,000 and placed on probation until the end of the year following his incident with Truck Series contender Ron Hornaday Jr. in the early laps of Friday's race at Texas Motor Speedway.

According to NASCAR, Busch could be suspended indefinitely "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 Joe Gibbs Racing driver lost any chance of contending for this year's Sprint Cup title after being unable to score any points in Sunday's race, which he watched from the top of his team's pit box at his sponsor's request. It remains to be seen if JGR will take any internal measures against Busch after his Sprint Cup sponsor Mars and manufacturer Toyota have expressed their disappointment over the driver's actions.
