NASCAR has fined Kyle Busch $50-thousand and placed him on probation for the remainder of the calendar year.  The penalties are 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.  NASCAR says Busch will be suspended indefinitely if there is another incident.  Busch will be allowed to race in this Sunday's Sprint Cup race at Phoenix International Raceway.
