The biggest question mark entering UFC 183 was going to be whether Anderson Silva's surgically-repaired leg was strong enough for the Spider to unleash his famous leg kicks.

Spider Shows Off Surgically Repaired Leg In Instagram Post

A recent post by the Spider to his Instagram account seemed to dispel any notions that his leg was too weak for the Octagon. Now, teammate Rafael Cavalcante is confirming that Silva is in top shape to take on Nick Diaz.

"I just returned from an injury, and I'm getting beat up in training. He's training hard, I'm really impressed," says Cavalcante, via MMA Fighting. "He's dedicated, and he will bring this win for the team. I wish he had this mental block because he's kicking me a lot, and he's kicking fucking hard.

"He's bigger than me, so he usually kicks me a lot in training because I like to close the distance when I'm fighting. He's kicking hard, thank God."
