IMPORTANT Melbourne big man Max Gawn has avoided a third knee reconstruction.

The 22-year-old had surgery on Tuesday after suffering a knee injury in Melbourne’s final-round clash against North Melbourne at Etihad Stadium on Sunday.

Gawn, who has had two knee reconstructions on his right knee, revealed on social media that he hadn’t torn his anterior cruciate ligament.

“Somehow i have dodged an acl! Only a scare! Surgery went well, 10 weeks and im back training #betterthen12months #finallysomeluckonmyside,” he said.

Gawn has played 26 AFL matches since making his debut in round 11, 2011.

He made nine appearances this season, including the final four rounds.

On Sunday, the Demons confirmed Gawn had likely avoided another ACL injury, instead damaging a meniscus.

Demons manager of football Josh Mahoney said: "Max has injured the same knee which was medically repaired when he ruptured his ACL in 2011.

“He is likely to require surgery to repair his damaged meniscus.

“A further review of his ACL graft will need to be undertaken during surgery to confirm this diagnosis.”

Gawn had his right knee reconstructed in 2009, before he was recruited by the Demons with pick No.34 in that year's NAB AFL Draft.

The injury-plagued big man reinjured the knee in the 2012 pre-season, wiping out his entire year, and a serious hamstring injury ahead of the 2013 season kept him sidelined for 12 weeks during the pre-season.
