Nat Fyfe has gone under the knife to repair his shoulder and will not play again in season 2021.
Fyfe posted on Instagram on Tuesday that surgery had gone well and he was now in recovery mode.
"Nat's pulled up well and the surgeon is reporting that everything went to plan," Fremantle's general manager of football Peter Bell said.
"It was the same surgeon who had operated previously on Nathan and he's spending a few days recovering in Melbourne currently."
Michael Walters is also unlikely to play again this season while Alex Pearce will miss Sunday's clash against Richmond suffering from concussion.
