In a post on Instagram confirming the news, Agyemang wrote: "Disappointed that results show a torn ACL. I am so grateful for all the kind words and the support from everyone. Recovery starts now, I will be back stronger than before. In all things I give thanks to the most high God, this test will surely turn into a testimony."
Statements from England, Arsenal and Brighton added words of support for the 19-year-old. "As a member of the Lionesses family, she has the full support of the FA and everyone associated with our England teams," the Football Association's update said. "Lionesses staff will remain in regular contact with Michelle and her club and be on hand to aid any aspect of her rehabilitation."
Arsenal and Brighton, meanwhile, both wrote that the clubs are "in close contact" as they strive to "determine a treatment and recovery programme for Michelle".
