The English club released a statement on Wednesday confirming the extent of the injury sustained by the 22-year-old attacker during the derby clash.
While Manchester City did not provide a specific timeline for Fowler's recovery and potential return to the pitch, they stated, "Mary will remain under the care of the club’s medical team and start her rehabilitation."
The club also extended their support to the young Australian international, saying, "Everyone at City wishes Mary all the best on a full and speedy recovery."
Mary Fowler has been a key player for Manchester City since joining the club in 2022, and her absence will undoubtedly be a significant blow to the team as they navigate the remainder of the season. ACL injuries are typically long-term, often requiring several months of rehabilitation before a player can return to competitive action. The news will also be a concern for the Australian national team as they look ahead to future international fixtures.
