The vacant KSW welterweight title is on the line at KSW 81 on April 22 as two of the division's top ranked stars clash for their chance to become the new KSW king of 170 lbs.

The undefeated Adrian Bartosinski (12-0) will go head to head with Artur Szczepaniak (9-1) in the biggest fight of their respective careers. 

Bartosinski made his KSW debut through the KSW reality TV show 'Only One' where he won all of his fights only to be forced from the finale due to injury. In the end he made his full promotional debut at KSW 59 and has won all four of his fights via stoppage. 

Szczepaniak burst into KSW in 2022 with two incredible finishes. Most recently, he KO'd Brian Hooi in less than a minute with a devastating headkick KO to earn his spot as a contender for the vacant title. 

XTB KSW 81 is available to watch live this Saturday, April 22, live around the world on www.KSWTV.com & the KSW App and exclusively on Viaplay in the UK, Poland, the Netherlands, Scandinavia, and the Baltics.
