Monster Energy/Pro Circuit Kawasaki's Dean Wilson suffered a severe laceration to the back of his knee at the opening round of the Lucas Oil Pro Motocross Championship at Glen Helen. Late in moto 2, Wilson caught a bump wrong and went over the bars down one of the steepest hills on the track—there are reports saying his engine might have cut out, as well. Early reports are that there is no structural damage to the knee. We will provide an update when more information becomes available.

Not sure if it was foot peg or what it was. It all happend so fast don't remember . It was a hair from my artery that coulda been bad but all ligaments and tendons are fine I just sliced my muscle a wee bit. So they cleaned it and sewed it up now just stuck in this shit hospital with antibiotics on the drip so it doesn't get infected.... Hate hospitals . Hoping to be out today
