Veteran referee Herb Dean had refereed four Anderson Silva fights prior to UFC 162 and seen others cageside. So when Silva began to clown Chris Weidman in the main event of this past Saturday’s pay-per-view, he did little else but pay close attention. Dean couldn’t hear what, if anything, “The Spider” was saying when he gesticulated at Weidman in the middle of exchanges. “I didn’t have any problem with it,” Dean told MMAjunkie.com Radio (www.mmajunkie.com/radio). “If that’s what he wanted to do. Everybody is in there for their own reasons, and he’s in there to do something great, and he challenges himself to be able to do his antics while he’s right there in the danger zone, and he was doing his thing.” Unfortunately for Silva, that led to a different result than any of the other times he stepped into the octagon and toyed with his opponents. For the first time in his octagon career, his antics caught up to him when Weidman landed a left hook that sent him crashing to the mat.
