Former UFC women’s featherweight champion Germaine de Randamie (8-3 MMA, 4-1 UFC) is out of next week’s UFC Fight Night 115 co-headliner, and the promotion is looking for a new opponent for Marion Reneau (7-3-1 MMA, 3-2-1 UFC).

MMAjunkie today confirmed with UFC officials that injury has forced de Randamie out of the contest. A timetable for her return was not immediately established.

Featuring a heavyweight headliner 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.

Former champ de Randamie was looking to fight for the first time since being stripped of her featherweight belt after refusing to defend it against top contender Cris Cyborg, who the Dutch fighter branded “a known and proven cheater.” The UFC’s decision brought to a close a strange chapter in the promotion’s history that saw de Randamie crowned champ after a hotly contested decision win over Holly Holm at February’s UFC 208.

Meanwhile, Reneau hopes returns to action for the first time since a March majority draw with Bethe Correia at UFC Fight Night 106 in Brazil. Reneau has endured mixed results since making her way to the UFC, opening her octagon run with victories over Alexis Dufresne and Jessica Andrade before falling short against Holly Holm and Ashlee Evans-Smith. This past November, she picked up a TKO win over Milana Dudieva before the draw with Correia.
