ALL eyes are on Sin City as Canelo Alvarez defends his middleweight world titles against Daniel Jacobs.

Who is on the Canelo vs Jacobs undercard?

CANELO will put his middleweight belts on the line on Saturday, May 5.

Kicking off the card is Sadam Ali, with the 'World Kid' looking to get himself back into title contention following defeat to Jaime Munguia last May.

Unbeaten Vergil Ortiz Jr continues his promising rise up the super lightweight ranks with a battle against Mauricio Herrera, whilst the first title fight of the evening pits Lamont Roach against the tough Jonathan Oquendo.

That bout will decide the WBO international super featherweight crown, before John Ryder and Bilal Akkawy go head-to-hed for the interim WBA super-middlweight crown.

A widely-disputed loss to Gennady Golovkin in 2017 convinced Jacobs that he was the man to beat, and when the heavy-handed Kazakh darling controversially went 0-1-1 with Canelo, the softly spoken Brooklynite was further convinced that the famed division, currently a Badlands of solid contenders, is a house with the New Yorker's name etched on the lease.

I went in there with Golovkin, the monster who no one wanted to face, and most would agree that I was the one who boxed better throughout and that my hand should've been raised.

"One hundred per cent I'm the best middleweight out there right now," declares Jacobs, passion in his breathless voice as he takes a brief respite from another demanding training session. "I went in there with Golovkin, the monster who no one wanted to face, and most would agree that I was the one who boxed better throughout and that my hand should've been raised. Golovkin has then gone on to defeat Canelo twice in my opinion, and although the official results say otherwise, I take a lot from my fight with Golovkin, and Golovkin's fights with Canelo to believe that I'm the best middleweight there is right now. May 4th in Vegas is when you see me make it official."
