DAYTONA BEACH, Florida (Reuters) - Kyle Busch will miss Sunday's NASCAR Sprint Cup Series season-opening Daytona 500 due to leg injuries sustained in a support event accident, according to the sport's sanctioning body.
Busch's Toyota slammed into an inside retaining wall at high speed late in Saturday's race and he was taken to a nearby hospital for treatment.
The 29-year-old driver had qualified fourth for the 57th edition of "The Great American Race" for a team owned by three-time Super Bowl-winning coach Joe Gibbs.
Kyle is the younger brother of 2004 champion Kurt Busch, who was suspended indefinitely from racing on Friday after a Delaware court ruled a finding of likely domestic abuse against former girlfriend Patricia Driscoll.
The 35-year-old Kurt failed to overturn the suspension when a three-member panel rejected his appeal on Saturday but the driver is awaiting the outcome of a last-ditch plea to NASCAR's final appeal officer in a bid to get back behind the wheel.
