I've thought about it it wasn't a sucker punch in traditional sense but it was a punch that shouldn't have been thrown. Yes the Ref did say fight and you are supposed to protect yourself at all times.
With that said they were still pulling away from the "Hug" when Floyd punched.
If the situation was reversed and Floyd was the one knocked out the same way Ortiz was Floyd and his team/associates would probably still be in the ring fighting!
There were many things that went wrong in the fight to allow the ending to happen the way they did and it was because of the Ref.
As a sportsman and in the spirit of competition the punch was an unfair punch but sportsmansip was thrown out of the window with the intentional headbutt.
Oh and I was rooting for Floyd.
