Sebastian Przybysz will defend his 135-pound belt against Jakub Wiklacz in the evening’s co-main event, while reigning 205-pound king Ibragim Chuzhigaev will face Ivan Erslan in another featured contest.

KSW 77 takes place at Arena Gliwice in Gliwice, Poland, and is headlined by a heavyweight showdown pitting Mamed Khalidov against Mariusz Pudzianowski.
Przybysz has posted a 7-1 mark since joining KSW.
