Injury has forced strawweight Aisling Daly (16-6 MMA, 2-1 UFC) to withdraw from a planned UFC Fight Night 93 contest with Michelle Waterson (13-4 MMA, 1-0 UFC).

MMAjunkie today confirmed with UFC officials that the promotion is currently seeking a new opponent for Waterson.

Featuring a heavyweight matchup between Andrei Arlovski and Josh Barnett, UFC Fight Night 93 takes place Sept. 3 at Barclaycard Arena in Hamburg, Germany. The night’s official bout order has yet to be revealed, but the entire event streams on UFC Fight Pass.

After losing her Invicta FC atomweight belt to Herica Tiburcio in late 2014, Waterson signed with the UFC in 2015, then moved up a weight class and scored a submission victory over Angela Magana. “The Karate Hottie” then was slated to fight Tecia Torres at UFC 194 in late 2015 but pulled out of the bout with a knee injury (and later suffered a hand injury). The 30-year-old is on a 7-1 run as she looks to head into her second UFC bout.

Daly, meanwhile, joined the UFC in 2014 after a quarterfinal-round finish on “The Ultimate Fighter 20.” Since her time on the show, the 28-year-old is 2-1 with victories over Alex Chambers and Ericka Almeida sandwiched around a decision loss to Randa Markos. Overall, the Cage Warriors vet and former NAAFS champ is on a 3-1 run.

The nature of Daly’s injury wasn’t revealed, and a timetable for her return wasn’t immediately established.

With the change, UFC Fight Night 93 now includes:

Andrei Arlovski vs. Josh Barnett

Jan Blachowicz vs. Alexander Gustafsson

Ryan Bader vs. Ilir Latifi

Michelle Waterson vs. TBA

Tae Hyun Bang vs. Nick Hein

Nicolas Dalby vs. Peter Sobotta
