Gennady Golovkin’s rematch with Canelo Alvarez is in limbo, but if the fight falls through, GGG still plans to defend his unified middleweight championship in the spring.

Alvarez tested positive for the banned substance clenbuterol twice last month, and on Friday, he was temporarily suspended by the Nevada State Athletic Commission. The Mexican star’s fate — as well as the fight’s — will be determined at a commission hearing on April 10.

In the meantime, both fighters are training as if the middleweight summit meeting will happen, but there are other boxers working hard, too, with a watchful eye.

Middleweight contender Demetrius “Boo Boo” Andrade is one of them.

“I am ready, willing and able to step to the plate on May 5th to fight Golovkin,” said Andrade, THE RING’s No. 6 middleweight. “I am always in the gym, and I will start [Voluntary Anti-Doping Association] testing right now. I guarantee that I will pass all the tests. I know other fighters can’t say the same thing.”

The former 154-pound titleholder has encountered tremendous difficulty trying to obtain a meaningful fight. The 30-year-old was woefully inactive, mostly against second-rate fighters, until he decided to move up to 160 pounds with an HBO bout against Alantez Fox in October.

Andrade (25-0, 16 knockouts) scored a unanimous decision, and over the last few months, intermittent talks were held to match him against fellow undefeated middleweight Sergiy Derevyanchenko, but the matchup never came to fruition.

So now, if Canelo-GGG 2 falls by the wayside, Andrade is hopeful this will be the break he’s been longing for.

“I am undefeated and a two-time world champion,” said Andrade, a native of Providence, Rhode Island. “Golovkin went through a period where nobody wanted to fight him. I am that guy now — the man nobody wants to fight.

“Everyone says ‘what does Demetrius Andrade bring to the table?’ Besides being the best American middleweight, and one of the top 3 middleweights in the world, everyone knows who I am, and they know how good I am.”

He hasn’t proven himself as one of the best 160-pounders yet, but there’s no denying Boo-Boo’s talent. He’s an athletic southpaw who can punch, move and possesses the amatuer pedigree to boot as a U.S. Olympian.

But so far, he’s been avoided, and he hasn’t face the proper caliber of opponent to bring the best out of him. That would change if he somehow landed a fight with GGG, of course.

“My question is to those who say that I don’t bring anything to the table: What did [former GGG foes] [Martin] Murray, [Osumanu] Adama, [Daniel] Geale, [Willie] Monroe and [Gabriel] Rosado bring to the table?

“None of the top contenders want to fight me so I believe that if Canelo is unavailable for May 5th, I want the opportunity to face Golovkin for the unified middleweight championship of the world.”

For now, Canelo-GGG 2 is still on, but if the fight is cancelled, it appears there will be no shortage of boxers willing to step up to the plate.
