“Me and my buddy Jordy Hoffman were on our final day of filming for another ski edit competition. We had a low light video of him doing a backflip, and tried the previous week to get another shot of it in daytime. The previous week, he over rotated it, and tore up the skin from his waist to his ribs. After taking a week off, he went at it again and this is what happened. Luckily, he didn’t break his neck or anything for that matter, but did suffer a pretty serious concussion.”
