The Collingwood Football Club confirms Dan McStay suffered a knee injury during last night’s Preliminary Final against the GWS Giants which will see him unavailable for the upcoming Grand Final.

Scans this morning revealed the 28-year-old sustained a high-grade medial collateral ligament strain.

General Manager of Football Graham Wright expressed the Club's disappointment with McStay’s prognosis.

"It's unfortunate to confirm that Dan has sustained a high-grade medial ligament injury during last night’s Preliminary Final with an expected recovery time of six to eight weeks,” Wright said.

“Dan has been an important part of our season this year and played an integral role in the last night’s victory against the Giants.

“We are all disappointed for Dan to miss the Grand Final, but we will all rally around him, and he will continue to be a part of the team’s preparations for the week ahead.”

The Club will provide a further update in due course.
