DALLAS -- John Force was able to stand and shuffle his feet Monday, and saying he's "lucky to have my legs" a day after a wreck at the O'Reilly NHRA Fall Nationals at Texas Motorplex hospitalized the drag-racing star.

Force has a compound fracture of his left ankle, a lacerated right knee, a dislocated left wrist and abrasions on two fingers on his right hand. He had screws inserted into his ankle and temporary pins placed in his wrist, said David Densmore, a spokesman for John Force Racing.

Force's prognosis is "very good" after six hours of surgery Sunday following the most severe accident he's experienced in more than three decades of racing, Densmore said.  "I just feel so helpless and vulnerable," Force said in comments released by Densmore. "I have had some burns, but I have gotten out of every crash and never had a scratch. I have never had a broken bone, so this is all new to me."

With the help of physical therapists, Force was able to stand Monday with his weight on his right leg and move both his feet, although doing so was painful.

"I gnawed off some fingers and toes when they had me trying to stand," he said.

Densmore said Force will miss the rest of the NHRA season, which has three scheduled dates remaining in Richmond, Va., Las Vegas and Pomona, Calif. Force is fourth in the Funny Car standings.
