Open the verified OKTAGON 94 event desk →The confirmed booking
OKTAGON announced on August 25 that Christian Eckerlin will face David Kozma at OKTAGON 94 on Saturday, September 26, at Deutsche Bank Park in Frankfurt. The promotion’s event page lists a 3:00 p.m. local start and identifies Eckerlin–Kozma as the event’s featured matchup.
What the rankings say
Verified August 25, OKTAGON’s fighter pages list Eckerlin at No. 9 in the welterweight division with an 18–8 record and Kozma at No. 7 with a 34–15 record. Kozma is a former OKTAGON welterweight champion; the promotion says his reign lasted 1,477 days.
The official announcement does not call the bout a championship fight or a formal title eliminator, so Fight Atlas is tracking it as a non-title welterweight matchup. Records and ranking labels will be refreshed if OKTAGON changes them before fight night.
