Antonio "Bigfoot" Silva slugged his way back into the UFC heavyweight title picture and a rematch with Cain Velasquez with impressive knockout victories over Alistair Overeem and Travis Browne.

Velasquez scored a dominating first-round TKO over Silva at UFC 146 in 2012 and went on to recapture the UFC heavyweight title with a unanimous decision over Junior dos Santos in December, but Silva’s most recent victories were so decisive they earned him a rematch against Velasquez at UFC 160 on Saturday in Las Vegas on pay-per-view.

"This is a whole new fight," Velasquez said. "Obviously we saw what Bigfoot can do in his past two fights. You can’t take him lightly, he is a tough competitor. He has really dangerous cuts in the octagon. So I don’t see this as anything less than a hard, grueling fight and that’s what I’m expecting."

Silva appears to be quite confident heading into the rematch.

"I’m sure that the first punch that I really land, he’s going to go down," Silva said. "I have a lot of respect for Cain Velasquez, I think he’s an incredible fighter, and I respect him as a person. But I’m very confident in myself and I feel very good going into this fight."

The co-main event for UFC 160 pits dos Santos, the former UFC heavyweight champion, against former K-1 champion Mark Hunt, who has seen a resurgence in his career with four consecutive victories in the UFC. The dos Santos-Hunt winner could be in line for a shot at the Velasquez-Silva winner.

"If I can beat Junior it should put me into the No. 1 spot," Hunt said. "I don’t see a reason why it wouldn’t."

It’s hard to say the ‘R word.’ I might never say the ‘R word.’

"I really think I’m walking away. I’m going to be 39. I just had my rib taken out. I’m having my third kid. My schools are doing well. What am I doing, looking for another pay day? It’s not really for that. I mean, it doesn’t stink, but it’s not really for that. Am I still trying to hold on for the glory? Glory is a drug, dude. I’m telling you, that’s the problem. It really is. I know why guys can’t walk away. I absolutely get it." …
