The contract stated no ground submissions. Kimbo's crew didn't know subs can be performed standing up. If they would have followed the rules he would have been choecked out 30 seconds into the fight. The contract also stated no kicks, kicks being described as any being hit with any part of the foot or shin. Well, they over-looked that as well. Apparently Kimbo's "dudes" didn't read the contract very well.
Ended with a haymaker? It would have ended with Kimbo laying unconsious from a choke 30 seconds into it if Kimbo's people didn't step in and start bitching about their so-called prodigy.
