I think also you have to give some weight to what BJ said it did'nt change the outcome of the fight. Though if nothing happens to GSP and I'm not saying something should some rules and regulations needs to be changed in between rounds.
I don't think anyone but fighter/cutman/doctor/ref should be allowed inside cage at any given time. Cornerman can bark orders thru the cage,doc can come in see if any cuts if not then leave. If a cut look at it,and let cutman vasoline it up.
Far as tourney? No real reason too don't think this calls for it unless he gets stripped of title..Which I seriously doubt and I don't think Dana's gonna strip it from him.
