This is the only answer. this was back when MMA wasn't even called MMA and the UFC was still on shaky legal grounds.
Shamrock and Severn were actually told in the locker room before the fight that they could be fined if they threw closed-fist strikes.
So the fight was just Shamrock and Severn circling each other warily. The entire fight.
Regulation time was 24 minutes, so they went into 3-minute overtime. Still no action. They went into an additional 3-minute overtime. STILL no action.
Without a doubt, the worst fight in MMA history. Especially with all the build up of champ vs champ. Motor City Madness, it was called. What a joke
It was so bad people were throwing stuff in the cage.
