Sergio was almost wearing trousers!!

Yeah that's why it was so damn embarrassing. It was like he was wearing extra long trunks to hide his knee braces. They just kept falling down all fight, the ref even had to stop the fight to fix his trunks. It was that bad. If I had to guess, in the 12th round vs Chavez he badly damaged his knees and the surgeries only messed them up more.

Let me just say that his performance against Chavez for the first 11 rounds was very impressive, I don't think he's that fighter anymore. The legs are just gone at the knee.
