The two had been scheduled to face each other on February 5. However, Ramirez fell ill at the 11th hour and the fight was nixed, with Mehmet Unal-Altin Zogaj headlining that evening instead. It proved a postponement and they will now headline an Eye of the Tiger event four months later than originally billed.

Ramirez, The Ring's No. 4-rated light heavyweight, got his big break after impressing during a training camp in Russia alongside former Ring and undisputed 175-pound world champion Artur Beterbiev.

He stunned then-unbeaten Braian Suarez with a first-round knockout in June 2022, scored a seventh-round stoppage of former world title challenger Adam Deines in a homecoming before taking out Jerome Pampellone for the WBA interim title on August 8.

"Being a champion isn't just about fighting, it's also about knowing how to handle the moments when you can't," Ramirez said in a press release.

"Not being able to step into the ring in February was difficult, but it now alllows me to come back even stronger. On June 4, there's no more waiting. I am the champion and I'm coming to show it to everyone—Richards first," he warned.

Meanwhile, Richards (19-1, 4 KOs) won British, Commonwealth and European super middleweight titles before edging a split decision winner beyond Carlos Gongora on the world scene in December 2021.

However, just as the skilled southpaw seemed primed to make his move he withdrew from a proposed Zak Chelli fight in November 2022 through dehydration. Since then, his career has been blighted by inactivity with only four fights since, including a shock sixth-round stoppage defeat by Steed Woodall in June 2024. Now, he enters this opportunity coming off a six-round points win against Cornish journeyman Dylan Courtney in September 2025.

Naturally, the 33-year-old Briton spoke of his excitement given the stakes involved.

"I am delighted to be back fighting at world level. The cancellation was unfortunate, but I'm glad it has been rescheduled. The date has changed bu the goal stays the same. Albert is a top opponent, I know what I bring to the table ... two of the world's best at 175lb facing each other. The goal is about becoming interim champion, putting myself in position to becoming WBA world champion," the southpaw stressed in the press release.

The undercard will see a host of fighters return to action against as yet unknown opponents. They include Ring's No. 7-rated light heavyweight contender Imam Khataev (11-1, 10 KOs) who makes his first start of the year.

Rising welterweight hopeful Christopher Guerrero (16-0, 9 KOs) is tabbed to appear, while Ring ambassador Jhon Orobio (17-0, 15 KOs) will look to build on an impressive fifth-round knockout over Yomar Alamo at 140 pounds.

Lightweight contender Dzmitry Asanau (12-0, 6 KOs) will aim to edge closer to a world title fight, while Avery Martin Duval (15-0-1, 8 KOs) also has 135-pound action on tap after a busy 2025. Rounding out the card, 2024 Olympic bronze medalist Wyatt Sanford (6-0, 2 KOs) is also slated to box at lightweight.
