Anderson DID NOT throw an illegal knee. Proof below.

During Silva vs Sonnen on this weekend there was a questionable knee thrown while Chael was down against the cage.  The initial perception is that Anderson threw an illegal knee to a downed opponent, but replays later prove this is false.  The angle that was aired on PPV placed Yves Lavigne directly in front of the action, leading most viewers to think the knee was illegal.   Bottom line, it was a legal knee.

And lets not forget this epic dodge!
