Former welterweight titleholder Luis Collazo will be after his fifth straight victory and his third stoppage during that run when the veteran southpaw meets ex-beltholder Amir Khan on the May 3 undercard of Floyd Mayweather Jr.'s RING and WBC 147-pound titles defense against WBA counterpart Marcos Maidana at the MGM Grand in Las Vegas.

In victory over Khan (28-3, 19 knockouts), Collazo (35-5, 18 KOs) looks to put himself in line for a shot at Mayweather (45-0, 26 KOs) should he get beyond the hard-hitting Maidana (35-3, 31 KOs).

"This fight is my whole career right in front of me. I believe if I beat Amir Khan I have a bigger future in boxing, and if I don't, I have to start from the bottom again," said Collazo, in a prepared release on Wednesday, his 33rd birthday.

"I am not looking beyond Amir Khan. He is my main focus. From here, whatever happens happens, but Amir Khan is all I'm thinking about right now. A win over Khan does put me in the Mayweather sweepstakes, but my sights are set on Khan."

Collazo was last in the ring for a second-round knockout of fellow left-hander Victor Ortiz in January, vaulting him onto a Mayweather-Maidana card that also includes three-division titlewinner Adrien Broner against Carlos Molina in Broner's 140-pound debut.

"When Floyd fights, everybody watches. Now to be able to fight in the fight right before he steps into the ring is tremendous. This is the highest plateau that one can fight on. You have to go out there and perform," said Collazo, who faces a man in Khan who was snubbed by Mayweather in favor of Maidana, whom Khan beat by unanimous decision in 2010.

"When Khan looks across the ring, he isn't going to see Floyd Mayweather. He is going to see Luis Collazo. I am the best…On May 3, 'The Moment' is going to be my moment…I believe this is the most exposure that I have seen in my career. I hope Khan is ready on May 3 to fight me, not someone else. It's going to be an explosive night not just for me, but for the boxing fans in general…Khan is going to fight the best Collazo on May 3. Whatever he said he said. Talk is cheap."

LEMIEUX-GUERRERO, CHARLO-OTA ON ADONIS STEVENSON-ANDRZEJ FONFARA UNDERCARD

Montreal middleweight David Lemieux (31-2, 29 KOs) will face former title challenger Fernando Guerrero (26-2, 19 KOs) and fellow 160-pounder Jermell Charlo (23-0, 11 KOs) will be matched against Charlie Ota (24-1-1, 16 KOs) on the May 24 undercard of a defense by RING and WBC champion Adonis "Superman" Stevenson (23-1-0, 20 KOs) against Andrzej Fonfara (25-2, 15 KOs) on Showtime from the Bell Centre in Montreal.

The winner of Stevenson-Fonfara could be in line to face IBF light heavyweight titleholder Bernard Hopkins, a 49-year-old whose unanimous decision dethroned WBA counterpart Beibut Shumenov on April 19 to make him the oldest man to unify belts in the sport. Hopkins already has twice become the oldest man to win a major belt, as well as the eldgest to defend one.

"Adonis Stevenson is a fighter we've been interested in for a long time. He was scheduled to fight on Showtime in 2012, but the card was canceled because of an injury," said ,” said Stephen Espinoza, executive vice president and general manager, Showtime sports.

"Now, following Stevenson's breakout year in 2013, we are even more excited to see him in action on the network. Add the two co-features, featuring powerful punchers in closely matched bouts, and this becomes yet another Showtime Championship Boxing event that you do not want to miss."
