By Dan Ambrose: The huge fight between #1 WBO, #2 WBC, #3 WBA Brian Viloria (36-4, 22 KOs) and unbeaten WBC flyweight champion Roman Gonzalez (43-0, 37 KOs) is now official for October 17th on the undercard of the IBO/WBA middleweight champion Gennady “GGG” Golovkin (33-0, 30 KOs) vs. IBF 160lb champion David Lemieux (34-2, 31 KOs) on HBO pay-per-view from Madison Square Garden in New York.

This is a really big deal because the Gonzalez vs. Viloria fight could prove to be an even more entertaining fight than the main event between Golovkin and Lemieux. With the Golovkin-Lemieux fight, it’s a fight that could very well end within two rounds because Lemieux is so inexperienced, and he’s fallen apart physically and mentally when he’s been moved up a level to fight good contenders in the middleweight division. Indeed, Lemieux was beaten by Marco Antonio Rubio by a 7th round stoppage loss in 2011.

Rubio is the same fighter that Golovkin knocked out with ease last year by a 2nd round knockout. But then again, Lemieux was really young when he lost to Rubio four years ago, and he’s since improved an great deal and has fixed his stamina problems.

“Done deal: Chocolatitobox vs. Brian Viloria officially announced this morning for 10/17 GGG-Lemieux undercard on HBO boxing PPV. Fantastic!” Dan Rafael said on his Twitter. “As far as Gonzalez-Viloria goes I haven’t been as geeked up for a little guy fight since probably Ricardo Lopez-Rosendo Alvarez I. #boxing. Manager for Brian Viloria tells me tonight it’s done deal that he’ll challenge Chocolatitobox for 112 title 10/17 on GGG-Lemieux PPV!!!!!!”

Viloria is one of those fighters that can look really good or look really bad. There’s no in between with him. If he comes out there looking sensational like he did in his last fight against Omar Soto, then Roman Gonzalez could be in for a really difficult night on October 17th. But if Viloria puts in a performance like he did in his loss to Juan Francisco Estrada, then Gonzalez will have an easy time putting Viloria away.

Viloria vs. Gonzalez promises to have a lot of fireworks for as long as it lasts.

Gonzalez looked great in stopping Edgar Sosa in 2 rounds last May on the undercard of the Golovkin vs. Willie Monroe Jr. card at the StubHub Center in Carson, California. Gonzalez absolutely destroyed a very good fighter in Sosa and made him look like a mediocre fighter. Gonzalez has way too much power for Sosa to deal with.

Viloria is a lot better fighter than Edgar Soso, so this still could be a difficult fight for Roman Gonzalez unless he brings his A-game and comes out there ready for business. If Gonzalez can put Viloria away like he did Sosa, then it’ll be a sign that Gonzalez needs to step it up and face Estrada again in a rematch or move up in weight to the super flyweight division to look or bigger obstacles to confront. It’s not going to help Gonzalez being matched against a bunch of guys that aren’t in his league and can’t handle his punching power.
