SAN JOSE, Costa Rica (AP)—Jeremy Lusk, an American freestyle motocross racer, died of head injuries two days after crashing while trying to land a backflip in competition. He was 24.
He had surgery in Calderon Hospital in San Jose to relieve swelling on his brain, but his condition worsened and he died Monday night, Metal Mulisha, his riding group, said Tuesday.
Lusk won a gold medal at the 2008 X Games. He was injured Saturday night when he failed to complete a full rotation while attempting a Hart Attack backflip and slammed headfirst into the dirt. 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.
Lusk, who lived in Temecula, Calif., is survived by his wife, Lauren.

This story hit me real hard. I've been watching these guys for years and it always seemed like they were invincible. I feel so bad for the family and Metal Mulisha. I hope to God no one on the internet posts the video anywhere - I don't want to see it.
