Oxfordshire's Bradley Smith crashed out of the 125cc Red Bull Indianapolis Grand Prix on Sunday when lying in second place.
The 19-year-old, from Forest Hill, near Oxford, was eight seconds adrift of his Bancaja Aspar teammate and eventual winner Nicolas Terol, and trying to stretch away from German Sandro Cortese when he exited the race at turn 11 with 11 laps remaining.
Smith landed heavily on the tarmac and appeared to be momentarily winded before he was able to get to his feet and walk away.
Spain’s Dani Pedrosa claimed his third win of the season with an impressive victory in the MotoGP.
He finished 3.575secs clear of home favourite Ben Spies.
