Jeremy Lusk, an awesome freestyle motocross rider, died of head injuries Tuesday after a horrible crash while trying to land a backflip in a competition in Costa Rica. Lusk was 24. We have the tragic crash video below.

Jeremy Lusk was taken to Calderon Hospital and was said to suffer severe brain damage and a possible spinal cord injury.

Jeremy Lusk won a gold medal during the 2008 X Games.  Lusk also won silver in Best Trick when he landed the first double-grab Hart Attack backflip. In addition he won a bronze helmet in Freestyle at the Moto X World Championships in San Diego.

Jeremy Lusk was nicknamed “Pitbull,” and was part of the Metal Mulisha freestyle motocross team.

Lusk was severely injured on Saturday night when he was unable to complete the full rotation while performing a Hart Attack backflip. Lusk slammed headfirst into the ground.

Jeremy Lusk died at 11:03 p.m. PT at the Calderon Intensive Care Unit in San Jose, where he was treated for major brain trauma and was in an induced coma to allow swelling of his brain to subside.

“He was in a medicine-induced coma as a protective measure, and the medicine was being reduced to see how his organism responded,” he said. “That didn’t mean he was going to wake up. He was in shock and that got worse last night, until he stopped responding and entered into cardiac and respiratory failure.”

Lusk died in the presence of his parents, Chuck and Gina Lusk, his wife Lauren and her parents. Metal Mulisha members Brian Deegan, Ryan Hagy, Cameron Steele and Erik Apple were also by his side.ron-jeremy
