Punching someone during an active contest is not unsportsmanlike conduct. Just like Mayweather's KO of Ortiz wasn't unsportsmanlike conduct. "Protect yourself at all times"
In the slow mo. Fabricio threw the sucker punch at the same time Ref did the TimeOut signal and the Ref assumed that Werdum was stepping aside. I'm trying to find a highlight, but in the vids it shows the Ref's back. There was another angle that showed it. Fighter's can't call Time Out themselves (unless your Bas Rutten) [ame="https://www.youtube.com/watch?v=AXCil2hK-hs"]UFC 203 Fabricio Werdum vs Travis Brown 2 FULL FIGHT HD - YouTube[/ame] (trying to find a better highlight vid)
