Nick Newell fought in XFC 15 last night. This guy only has a small portion of his left forearm and he used it to create a heel hook submission.
I normally do not agree with a handicapped individual being granted a license to fight. But as it turns out Nick has just enough of an arm to be dangerous. We didn't get to see him strike with it but we did get to see him using it for head control after he took down his opponent. In close quarters his shorter arm can actually be an advantage. It will be interesting to see if he can do what no one else has done before in turning his physical handicap into an advantage in the cage but damn if that finish didn't make me laugh in surprise.
