Plan C for Jermall Charlo was revealed Tuesday by Premier Boxing Champions and Showtime.

Those partners announced in a joint press release that unbeaten the WBC middleweight champion will make an optional defense of his 160-pound crown against Maciej Sulecki on June 18. Showtime will televise Charlo-Sulecki as a 12-round main event from a venue to be determined in Houston, Charlo’s hometown.

Charlo had hoped to end a long layoff by challenging Canelo Alvarez in a super middleweight championship match May 7 in Las Vegas. The Mexican superstar ultimately chose to move back up to the light heavyweight division to battle unbeaten WBA champion Dmitry Bivol that night at T-Mobile Arena in Las Vegas.

With Alvarez contractually tied to DAZN at least through the end of this year, Charlo’s handlers turned their attention toward another Mexican opponent, Jaime Munguia.

PBC founder Al Haymon thought he had a deal in place last week for Charlo (32-0, 22 KOs) to meet Munguia (39-0, 30 KOs) in Showtime’s main event June 18 or at some point in July.

Representatives for PBC and Oscar De La Hoya’s Golden Boy Promotions also discussed pay-per-view options for Charlo-Munguia. Whether it was distributed by Showtime, DAZN or both, putting that fight on pay-per-view would’ve drawn backlash from consumers who have grown increasingly frustrated by overuse of that expensive platform by promoters, networks and streaming services.

Ultimately, negotiations ended without the consummation of a deal for Charlo-Munguia. Haymon then turned his attention over the weekend to finalizing a deal for Charlo-Sulecki.

Warsaw’s Sulecki (30-2, 11 KOs) has lost only a pair of 12-round unanimous decisions to former WBO middleweight champ Demetrius Andrade (31-0, 19 KOs) and onetime IBF middleweight champ Daniel Jacobs (37-4, 30 KOs).

Charlo (32-0, 22 KOs) will fight for the first time in almost exactly a year when he steps into the ring to oppose Sulecki. In Charlo’s most recent action, he withstood a tougher-than-anticipated challenge from Mexican contender Juan Macias Montiel (23-5-2, 23 KOs) last June 19 at Toyota Center in Houston.

Tijuana’s Munguia, meanwhile, is left without an option for a middleweight title fight next, despite that he is the number one contender for Charlo’s championship and the WBO interim title.

In addition to a deal for the Charlo fight on Showtime, Munguia’s co-promoters, Golden Boy and Zanfer Boxing, were presented with an opportunity to fight for the vacant WBO belt against Kazakhstan’s Janibek Alimkhanuly.

Munguia’s handlers didn’t adhere to the WBO’s protocol once the period for voluntary negotiations with Alimkhanuly’s promoter, Top Rank Inc., ended. Rather than calling a purse bid for Munguia-Alimkhanuly, the WBO instead ordered a bout between the second-ranked Alimkhanuly (11-0, 7 KOs) and England’s Danny Dignum (14-0-1, 8 KOs), who is ranked fifth by the WBO.

Representatives for Alimkhanuly and Dignum were granted 10 days to negotiate last week. If those two sides can’t come to an agreement, the WBO will order a purse bid for Alimkhanuly-Dignum.
