The midfielder hyperextended his right knee in the first half of the match, both he and the club initially believed it was only a minor injury. He will miss the entire 2017 season.
The 24-year-old is off contract at season’s end, he was set to enter his fourth season for the Crows. He has played fourteen games for the club so far in a career that has been riddled with injuries.
Crows head of football Brett Burton said the club will full support Ellis-Yolmen through his rehabilitation.
“The injury is really disappointing for both Cam and the club,” Burton said.
“We were excited about him pushing his claims for round one selection.
“We will consult a specialist this week with the view to Cam having surgery, which will unfortunately rule him out for the season.
“I have no doubt Cam will be diligent in his rehabilitation and we look forward to supporting him through that process.”
