Since losing to Lyoto Machida at UFC 94 in 2009, UFC light heavyweight Thiago Silva had managed only one win in the UFC.  With two banned substance suspensions to his credit, the Brazilian has seen two UFC wins overturned and ruled “No Contest’ over the past two years. On Saturday night in Fortaleza, Brazil, after six months of inactivity due to an aforementioned suspension, Silva defeated former Strikeforce light heavyweight champion Rafael “Feijao” Cavalcante via first round knockout, effectively rejuvenating his career. Round one saw the Sao Paulo natives meet in the Octagon without touching gloves.  Silva had his usual stone-faced look of determination, as UFC newcomer Feijao stood with a postured look of calm confidence. The opening bell sounded and Cavalcante pressured early looking to land a powerful right hand.  Silva backed away, and in the opening seconds looked rigid and slow. As the frame wore on, however, Cavalcante’s pressure began to slow, and Silva’s momentum increased.  Silva peppered Feijao with an assortment of jabs and distracting leg kicks
