KSW 100 takes place in Poland this Saturday night and for such a historic event in the promotion's history, they're unsurprisingly bringing out the big guns.
With a super fight in the main event and three title fights elsewhere on the card, KSW has pulled out all the stops once again to try and make this a night to remember.
In the main event, Mamed Khalidov continues his run of super fights when he faces off with the undefeated Adrian Bartosiński.
Bartosiński will be moving up to middleweight for this fight after successfully defending his welterweight title twice, including a huge win over the two-weight world champion, Salahdine Parnasse, last December.
The co-main event features the return of the most dominant champion in the sport, KSW's heavyweight king Phil De Fries, who will be looking to make his eleventh title defence.
He will collide with Darko Stošić in a rematch of their first meeting back in 2022 where the champion retained via a finish in the fifth round.
Stošić has won his last four fights in a row via knockout in order to earn his second shot at De Fries's crown.
In the night's second title fight, Rafał Haratyk defends his light heavyweight title in a rematch with Marcin Wójcik.
The two Polish fighters last met in the 205-pound tournament that took place earlier this year where Haratyk was crowned the champion after winning two fights on the same night, stopping Wójcik in the first round before winning a split decision against Damian Piwowarczyk.
In a break between title fights, two dangerous heavyweight strikers will meet when the former PFL finalist Matheus Scheffel looks to hand Arkadiusz Wrzosek the first loss of his MMA career.
Wrzosek has finished all three of his recent fights in KSW in the first round and comes from a background in GLORY kickboxing where he famously knocked out Badr Hari.
In the last of the three title fights, Robert Ruchała returns to defend his interim featherweight title against Kacper Formela in the hopes or earning a rematch with Salahdine Parnasse.
The next two bouts see ranked contenders at both welterweight and middleweight collide as Andrzej Grzebyk faces Wiktor Zalewski whilst Piotr Kuberski meets Damian Janikowski.
Opening up the main card is a welterweight bout between former title challenger Igor Michaliszyn and the "Latvian Express", Madars Fleminas who earned his first win in the promotion last time out after making the switch from his former home of Cage Warriors.
With all of this and more in mind, the Arena Gliwice is set for another incredible chapter in the history of KSW on November 16.
