LAGUNA SECA, California (AFP) - Spain's world title hopeful Dani Pedrosa has been forced out of Sunday's United States Grand Prix after failing to recover from injuries suffered in a fall in Germany last week.

"Dani won't take part in either qualifying or the race," said a Honda spokesman.

Pedrosa, currently second in the world championship, suffered a fractured wrist and a badly damaged ankle in last Sunday's German Grand Prix but still flew to America in a desperate attempt to ride.

Earlier Saturday, his agent Albert Puig said Pedrosa had been hopeful of taking part.

"He underwent an operation on Monday and he was very courageous to come here. The track is very demanding," said Puig.

Pedrosa had set a searing pace in the wet conditions in Germany and was over five seconds ahead when he came to grief after five of the 30 laps.

Australian world champion Casey Stoner went on to win - his third successive victory - while Valentino Rossi was second, giving the Italian enough points to overhaul Pedrosa at the top of the standings.

Rossi leads Pedrosa by 16 points while Stoner is four points adrift of the Spaniard.
