Not over. Conlan performed more than good enough to suggest he will come back. That was the best Conlan I've seen.
One the nastiest KO's you will ever see. He was out then recieved a couple more before collapsing through the ropes We will have to see what he is like in the rematch. I am sure if he wants the rematch it will be accepted, and plenty of eye balls will tune in. It was a great fight!!!
Man has a family to feed. Still young and can fight. As long as he is medically cleared i dont see why he would quit at this stage.
