As the 2025/26 European club season shifts into full gear, a spike in ACL injuries is shedding new light on the increasingly dense women's soccer calendar.

Germany and Bayern Munich star Lena Oberdorf ruptured her right ACL during her club's Bundesliga match on Sunday, just weeks after the 23-year-old midfielder returned to play from rehabbing the same injury — in the same right knee.

"To now face a second such setback is incredibly hard," said Bayern Munich director of women's football Bianca Rech. "We are fully by Lena's side, will support her as best we can in her recovery and be there for her in every way."

Oberdorf is far from alone, with over 20 ACL injuries impacting multiple women's soccer leagues across the world in just the last three months.

Arsenal goalkeeper and Austrian international Manuela Zinsberger went down with an ACL tear during the Gunners' 2025/26 Champions League match last week, joining standouts like midfielder Sarah Zadrizil (Bayern Munich/Austria), striker Sophie Román Haug (Liverpool/Norway), forward Liana Joseph (OL Lyonnes/France), and midfielder Maite Oroz (Tottenham/Spain) on the injury's mounting hit list.

ACL injuries have long plagued the women's game, with FIFPRO recently developing the Project ACL research initiative to investigate and alleviate the issue.
