Ramirez (20-0, 17 KOs) represented Venezuela at the 2016 Olympics and turned pro in 2018, notching 10 straight stoppages before going the distance for the first time against durable Argentine Facundo Nicolas Galovar in March 2022. Since then, only two of his opponents have heard the final bell. In February, he kicked off his 2025 campaign with a third-round TKO over once-beaten Marko Calic. Flannery (13-0, 11 KOs) is a 28-year-old puncher who was born in the United Kingdom and lives in Thailand, where most of his pro wins have ended via knockout. He last fought in January in Thailand, snatching the WBC Asian light heavyweight belt with a third-round stoppage over Rattawut Thongaram.
