FEN 34: Full Lineup, Preview & How To Watch FEN MMA returns this week, with FEN 34 going down on Friday, May 28th. The Polish promotion has put together a nine-bout lineup that contains several intriguing matchups, most notably the main and co-main events. In the main event, light heavyweights Paweł Trybała and Łukasz Borowski clash in an anticpated rematch. The pair first fought at FEN 31 in a bout that saw both men throwing bombs right from the opening bell. It was an entertaining affair that came to a halt a minute into the second round after Trybała burst Borowski’s left ear with a shot that caused heavy bleeding. It was a frustrating ending to what had been a classic old-fashioned scrap. The demand for a rematch came from both fans and fighters, and thankfully the FEN matchmakers have obliged.
