X GAMES gold medallist Jeremy Lusk, an American freestyle motocross racer, has died of head injuries caused when he crashed while trying to land a backflip in competition.
Lusk, 24, was injured in Costa Rica on Saturday when he failed to complete a full rotation while attempting a Hart Attack backflip and slammed headfirst into the dirt.
Jorge Ramirez, chief of the intensive care unit at Calderon Hospital where Lusk was put into a medicine-induced coma, said the motocross racer suffered severe brain damage and a possible spinal cord injury.
Lusk crashed in almost identical fashion in the freestyle semifinals at the 2007 X Games but was not hurt.
He had a successful 2008 season, winning freestyle gold at the X Games and silver in best trick when he landed the first double-grab Hart Attack backflip.
He won a bronze helmet in freestyle at the Moto X World Championships in his hometown of San Diego.
Ramirez said Lusk died with his parents and his wife, Lauren, at his side.
Lusk lived in Temecula, California.
