function not found Former UFC middleweight champion Anderson Silva said following his UFC 162 knockout loss to Chris Weidman that he didn’t want to exercise his option for an immediate rematch.  Mark Munoz , however, is ready to fill the void.  “I worked hard for this fight.  He has my respect because he is the best now.  Chris is new champion.  Chris is the champion now.  I finish my work.  I no more fight for the belt.   I fight for the belt for a long time.  I’m tired,” said the long-time titleholder following his knockout loss to Weidman. If Silva declines, Munoz is more than willing to step up.
