IBF, IBO, WBA, WBC middleweight world champion Gennady Golovkin (37-0-1, 33 KOs) is really pumped to get back in the ring on Cinco De Mayo weekend, May 5th.

Golovkin will face Vanes "The Nightmare" Martirosyan at the StubHub Center in Carson California.

Vanes is the replacement opponent for Mexican superstar Saul "Canelo" Alvarez, who was initially scheduled to face Golovkin on the same May date at the T-Mobile Arena in Las Vegas.

Canelo was suspended for six months by the Nevada State Athletic Commission, after the boxer tested positive for the banned substance clenbuterol back in February in two separate drug tests.

Golovkin and Canelo fought to a controversial split draw last September.

Because Canelo will be cleared to fight by August, many expect their rematch to take place in September, during Mexican Independence Day weekend.

Martirosyan (36-3-1, 21 KOs) is a huge underdog in the contest. He is moving up from the junior middleweight limit of 154-pounds, lost three of his last six fights, and has not fought since May 2016 when he lost a twelve round decision to Erislandy Lara.

Even with all of the facts on the table, Golovkin is expected a very tough fight when he steps in the ring, and brushes away some of the comments from the critics who believe the contest will be easy.

"He's a real guy. I'm very excited because I'm coming back to boxing. I have an opponent. Vanes is not an easy guy. He's strong, he's tall. He has a strong team," Golovkin said.

Tom Loeffler, who promotes Golovkin, is expecting a lot of drama in the contest - because Vanes like to come forward and fight.

"[Golovkin is] also really excited because he won't have to look for Vanes. With Canelo he was chasing him around the whole ring. There is going to be a lot of excitement," Loeffler said.
