Mamed Khalidov, Borys Mankowski Top Lineup for KSW Stadium Show in Warsaw on May 27

A champion vs. champion showdown between Mamed Khalidov and Borys Mankowski will serve as the main event for Polish promotion’s Konfrontacja Sztuk Walki’s massive stadium show in Warsaw on May 27.

KSW recently announced the pairing, which will be held at a catch-weight. Entitled KSW “Colosseum,” the event will take place at PGE Narodowy, a retractable roof stadium with a capacity of approximately 58,415 that is home to the Polish national soccer team. Former “World’s Strongest Man” Mariusz Pudzianowski and Olympic wrestling bronze medalist Damian Janikowski are also expected to compete at the event, although opponents have not been named for either man.

Additionally, heavyweight champion Fernando Rodrigues Jr. will face Marcin Rozalski, while Marcin Wrzosek will take on Kleber Koike Erbst in a featherweight title bout.

Khalidov, the promotion’s reigning middleweight king, enters the matchup on a 12-fight winning streak. During that time, the 36-year-old has bested the likes of James Irvin, Matt Lindland, Jesse Taylor, Kendall Grove, Melvin Manhoef and Michal Materla, to name a few.

Mankowski captured KSW’s welterweight crown by submitting Aslambek Saidov in May 2014. “The Tasmanian Devil” has defended the strap in victories over John Maguire, Jesse Taylor and David Zawada and has nine of his last 10 fights overall.
