Injury has forced German fighter Nick Hein (14-2 MMA, 4-1 UFC) out of next week’s UFC Fight Night 115 event in Rotterdam, and company officials are currently seeking a replacement opponent for Zabit Magomedsharipov (12-1 MMA, 0-0 UFC).

MMAjunkie today confirmed the change to the card with UFC officials.

Featuring a heavyweight matchup between Stefan Struve and Alexander Volkov, UFC Fight Night 115 takes place Sept. 2 at Ahoy Rotterdam in the Netherlands. The entire card streams live on UFC Fight Pass.

Despite winning four of his five UFC fights and riding a three-fight winning streak, Hein was looking to drop down to 145 pounds for the bout. That move will now be delayed, though a timetable for his return wasn’t immediately established.

Magomedsharipov, meanwhile, has only seen the judges scorecards twice in his career, and hasn’t done so since November 2013. The Dagestani fighter brings an eight-fight winning streak into his octagon debut, which will mark his return to competition after a nearly one-year layoff.
