Looks like it damaged his heart, but it was still working enough that he was able to get up and walk away. But I'm sure there were complications and they noticed how bad it was when they checked his vitals. On top of the concussion...the damaged heart likely screwed up bloodflow to the brain as well, so I'm sure he had numerous unrecoverable issues with the heart and brain.
I saw some of the wimmens jumping around on skis competition last weekend. One of them did a back plant on the edge of a hill and neatly snapped her neck. She couldn't move anything south of her chin. Took a long time to drag her off and all the other gals were weepy, then the ref shouted play ball. First one down the hill crashed. Second crashed. 3rd made it, 4th crashed. Then after a while one slid into the fence and snapped a femur and there was another long weepy delay. And now they are allowed in combat?
Just watched the video. Wow yeah he didn't hit that jump fast enough cause him to under rotate. He should of known it wasn't gonna work when he came off the ramp (when you do stuff like this you know if you're gonna make the landing as soon as you're in the air. I had to pull the eject handle on my quad plenty of times and bailed. Being off by just a mph is the difference between landing and crashing
When your helmet looks like a crushed grape..it is never a good thing......and the whole mechanics of that accident....if he was allowed to walk off....I can see there being a huge lawsuit against the Xgames and the medical staff they contracted to cover the event.
