If you have a weak stomach, I suggest not watching the highlights. Best leaped over a defender to score the touchdown, and landed squarely on the upper part of his back/neck area. Oregon State players immediately formed a prayer in the end zone and Best was taken off on a stretcher with oxygen to assist his breathing. Nobody likes to see injuries like this, we hope he is okay.
UPDATE: Best has a concussion and has movement in his arms and legs per FSN announcers working the game.
