Broner says he will knock DeMarco out

Unbeaten American star Adrien Broner says he'll put Mexico's Antonio DeMarco away inside the distance when they meet on November 17.

DeMarco, the reigning WBC lightweight champion, has only been stopped once - when he retired on his stool after nine rounds against the late Edwin Valero in 2010.

"I'm not coming just to win this fight, I'm coming to knock DeMarco out," Broner, 23, said.

"This fight is speed vs. power and it's going to be just another day in the ring for me.

"Going up in weight is going to be different and I know he can hit, but you can't hit what you can't see and I'm too fast and furious for him. Power is nothing if you can't connect; it's like moving a sack of rocks."

DeMarco responded:  "Broner talks a big game but he's never been in the ring with a hungry Mexican fighter like me.

"I wanted this fight from the moment it was offered to me because I know I'll be the first person to beat Broner and put him in his place. When I put my hands on him, he'll regret his decision to move up to my division."
