Europe's leading Mixed Martial Arts promotion KSW will make its Irish debut on 22 October, as KSW 40 comes to Dublin's 3Arena.
KSW 40 will be only the organisation's second event outside of Poland, following the successful KSW 32: Road to Wembley event in London at the end of 2015.
Fighters Only magazine called May's KSW 39: Colosseum "The Greatest Show on Earth" after the event smashed previous MMA record attendance numbers.
KSW 39 was the second most-attended MMA event in the history of the sport and the biggest-ever in Europe, and the promoters expect more records to be set in October as enthusiastic Irish MMA fans and Dublin's Polish community come out in force to KSW 40.
The two main event fights in Dublin will feature some of the biggest names in KSW.
Five-time world's strongest Mariusz Pudzianowski will square off against James "The Hammer" McSweeney, while the undefeated KSW lightweight champion Mateusz Gamrot will take on Ireland's own "Stormin" Norman Parke in a hotly-anticpated rematch.
Former KSW middleweight champion Michał Materla will battle the dangerous Brazilian Paulo Thiago, while Ireland's former Cage Warriors champion Chris Fields faces Polish powerhouse Michał Fijałka, and Irish BAMMA title contender Paul Redmond goes up against Łukasz Chlewicki.
eir Sport have the exclusive rights in Ireland to show KSW 40 from the 3Arena on Sunday, 22 October.
