Toni Elías
He had a wildcard ride for Gresini Honda at the United States Grand Prix held on July 22, 2007 at Mazda Raceway Laguna Seca, replacing the injured Toni Elías. He pulled out of the MotoGP race early because he was unable to get a feel for the unfamiliar Honda RC212V he was riding. He also raced the AMA Superbike round at the same meeting Duhamel had a crash while practicing at Road Atlanta on August 8, 2007. He suffered a lacerated liver, and a perforated and bruised lung.
