Contingency plans are being made for May 5 with Canelo Alvarez’s availability in serious doubt.

Gennady Golovkin still plans to defend his three middleweight titles on that date in Las Vegas, with or without Canelo, who is temporarily suspended by the Nevada commission stemming from his anti-doping violation.

To that end, promoter Tom Loeffler made an offer to Mexican prospect Jamie Munguia for a middleweight title bout with Golovkin, sources with knowledge of the discussions told THE RING. The sources, who requested anonymity, were not authorized to speak publicly on the matter.

When asked if Munguia was being considered as a replacement, Loeffler told THE RING via text message, “Just exploring all the options, still waiting for [the] Commission,” to decide Canelo’s fate.

Munguia (28-0, 24 knockouts), THE RING’s 2017 Prospect of the Year, is undefeated but he campaigns at junior middleweight and has yet to face anyone remotely on the world-class level. The 21-year-old fits the bill as someone who would present a style similar to what Golovkin has been training for and also wouldn’t be a threat to score an upset victory and thwart an eventual Canelo-Golovkin rematch.

Munguia is viewed as the front-runner to land the GGG fight if Canelo is handed a ban at his April 18 commission hearing in Las Vegas as expected, according to the source, but that has not been confirmed with Loeffler or Munguia’s promotional representation, Zanfer.

But another possible opponent for the undefeated Kazakh is Irishman Gary “Spike” O’Sullivan, a rough-and-tumble brawler who also wouldn’t figure to present much of a challenge to GGG.

For now, Canelo-GGG 2 remains on, but the prospect of the highly anticipated encore taking place on May 5 as planned received a serious blow on Thursday when it was learned Nevada State Athletic Commission executive director filed a formal complaint against the Mexican star seeking disciplinary action.

It would certainly make financial sense for Golovkin’s side to choose a Mexican replacement opponent with the fight scheduled for Cinco De Mayo and many Mexicans already booked to travel to Las Vegas.

And if it’s Munguia, he could become part of a trivia question down the line as Golovkin seeks to match Bernard Hopkins’ record 20 consecutive middleweight title defenses in his next fight.

It remains unclear if Golovkin’s fight will be moved to another venue if Canelo is forced to withdraw, in addition to whether the bout is switched to HBO as opposed to the network’s pay-per-view arm.
