While competing in the best trick event Thursday night in the X Games in Los Angeles, Pastrana fractured his right foot and ankle when his attempt at completing a “720” went awry and he crashed on landing.
The trick features two backflips on a motorcycle and one spin.
ESPN, which is broadcasting the X Games, reported Pastrana will require surgery for his injuries.
Early Friday, the Pastrana Waltrip Racing team withdrew its entry from Saturday night’s Kroger 200 at Lucas Oil Raceway in Clermont, Ind. Pastrana’s next scheduled Nationwide race is Sept. 9 at Richmond, Va.
In a statement to ESPN early Friday morning after having X-rays at a Los Angeles hospital, Pastrana said, “I am sorry this happened and will be back in action as soon as I can. I look forward to Pastranathon 2012 at X Games 18.”
