Tried to find it on their site but couldn't. It shows a list of suspended fighters on their site, including the likes of Ryan Burnett and David Haye, and references that reg as to the reason they are suspended.
A surprisingly decent question from a knuckle-head such as yourself. It's a standard medical suspension - Burnett had a bad cut, Haye obviously injured. Lots of guys have it if they lose by KO.
