Mexico's super middleweight contender Marco Antonio "Veneno" Rubio is a common opponent for middleweight champions David Lemieux and Gennady "GGG" Golovkin - who on October 17th will face each other in an IBF/IBO/WBA title unification from Madison Square Garden in New York City.

Rubio and Gabriel Rosado are the only two common opponents for the middleweight punchers. Rubio, like everyone else, expects a knockout ending.

In 2011, Rubio stopped a very green David Lemieux (who was 25-0) in the seventh round. Lemieux was well ahead on the cards and working Rubio over badly in the early rounds, but he ran out of gas and was stopped.

Rubio fought Golovkin a year ago and was stopped in the second round. The Mexican fighter says he was a dead man in the ring after struggling with weight for the entire training camp. Rubio failed to make weight for that fight and moved up to 168-pounds in his next bout.

"I see a lot of possibilities for Lemieux, he hits hard. We fought four years ago, he was inexperienced, he hits very hard and has great potential. Not to disparage anyone, but with 'GGG' I was a dead man because I was struggling with the weight. I was in the sauna the entire time and with Lemieux was one hundred percent. I would even say that Lemieux can win because he is a complete fighter and hard hits. When the time comes, he will have a chance," said Rubio to ESPN Deportes.

"Obviously GGG is the favorite because he is more dangerous, but do not doubt that David might surprise him. We have not seen anyone who can hit Gennady as [hard as] Lemieux can. It will be a very good fight, a war in which people can not blink at all."
