An injury has forced Stephan Bonnar to the sidelines, and UFC newcomer Ronny Markes has stepped in as a replacement.
He has agreed to fight fellow light heavyweight Karlos Vemola at August’s UFC on Versus 5 event.
UFC on Versus 5 takes place Aug. 14 at Bradley Center in Milwaukee, and the night’s main card airs on Versus. Bonnar vs. Vemola had been slated for the broadcast but could be demoted to the preliminary card.
