Greg Biffle's shoulder injury, sustained in a testing accident at Las Vegas Motor Speedway, forced him to miss the weekend's Busch Series awards banquet after doctors advised him not to travel.

Biffle's test ended early on Thursday when he made hard contact with the wall between turns one and two, the impact big enough to knock the fuel pump off the car and leave Biffle spinning away in flames. Kyle Busch, who was following Biffle closely, helped the veteran from his car but, although the Ameriquest driver appeared not to be badly injured, his shoulder was later diagnosed as dislocated.

“That was a really hard hit and we lost a good car,” Biffle said later, "I cut a right front tyre and made heavy contact with the wall. As a result of the incident, I dislocated my shoulder and have been advised by my doctors to remain in Mooresville today for further assessment of the injury.

"For that reason, I was unable to attend this year's NASCAR Busch Series Banquet. I would like to extend my sincerest apologies to NASCAR, the Busch Series and Ameriquest for my absence. It was a privilege and a great pleasure for me to continue to be a competitor for Roush Racing, Ameriquest, Brewco Motorsports and Ford Motor Company in NASCAR's Busch Series this season.

"I love racing in the Busch Series and I plan to continue to do so for many years."
