Former boxing champion Floyd Mayweather Jr. says he will use an upcoming exhibition bout to sharpen his skills for events planned later this year. Promoters confirm that Mayweather will meet Greek kickboxing star Mike Zambidis in a “full-contact exhibition showdown” in Athens on June 27. The pay-per-view event is scheduled for the Telekon Center at the OAKA Olympic Complex. Mayweather, 49, retired from boxing in 2017 after finishing his career with a 50-0 record and multiple world titles. Since retiring, he has appeared in exhibition fights. One previously announced exhibition involving Mayweather and former heavyweight champion Mike Tyson did not take place, but the Zambidis meeting is presented as a separate matchup. Across reports, both outlets describe the bout as an exhibition featuring full-contact rules, with Mayweather framing it as preparation for what he intends to do later in 2024.
