Camille Estephan, manager of IBF middleweight champion David Lemieux (34-2, 31KOs), is expecting a knockout victory when they face WBA/IBO middleweight champion Gennady "GGG" Golovkin (33-0, 30KOs) in their HBO Pay-Per-View unification showdown.

The fight takes place on October 17th from New York's Madison Square Garden. 

Lemieux is the big underdog coming in. He has two common opponents with Golovkin. Both of them scored bruising knockouts over Gabe Rosado, but they had far different results with Marco Antonio Rubio.

Lemieux, an inexperienced young fighter, was battering Rubio for several rounds before completely running out of gas and getting stopped. Golovkin blew out Rubio last year in two rounds, although the Mexican veteran claimed to have extreme weight issues and failed to make the middleweight limit for that contest.

Everyone is talking about Golovkin coming in and that will change, says Estephan, after Lemieux scores an eye-catching knockout to walk away with several world titles and Golovkin's undefeated record.

"Believe me, after the 17th, on the 18th, everybody is going to say 'did you that guy Lemieux?' Lemieux will win by knockout. It's going to be a great war. It's going to be two guys who want it really badly, but it is going to be our night and Lemieux is going to come out with his hands raised after a beautiful knockout," Estephan said.
