I say fluke knee because it was only because Bisping was looking at the ref, Herb who was picking up the mouthguard, and coming over, looking like he was going to give it to Bisping. Bisping then gets kneed in the face while looking at Herb.
Bisping came into round 4 wobbly and flat footed. I thought he was about to trip on his feet. Prior to that knee he was looking sharp, even in the beating he took in the last 30 seconds, he still would arguably winning the round, and definitely would have come into the 4th sharp were it not for the knee.
Silva knee something was going on, Bisping was looking and talking to the ref, signaling that he had no mouthguard. The ever respectful Anderson just kept going. Anderson is no idiot, he knows when he'll land shots when the opponent is looking at him. He will of course know when he'll land shots when the opponent is NOT looking at him.
Silva deserves both the judging loss and moral loss in my opinion.
