Hawthorn's Jarman Impey will require surgery to repair his ACL after he suffered a knee injury during his side's win over Geelong on Sunday.

Impey landed awkwardly in the second quarter of Sunday's game at the MCG, and was taken from the field in the hands of the trainers.

The Hawks were hoping Impey was going to avoid the dreaded ACL injury, although unfortunately that wasn't the case.

โ€œWe were hopeful yesterday that there would be no ACL damage, but unfortunately the news was confirmed this morning,โ€ GM-Football Graham Wright told the club's website.

โ€œHe will undergo surgery this week.

โ€œItโ€™s obviously really disappointing for both Jarman and the club, but he is in high spirits and remaining positive.

โ€œJarman is such a valuable player for us and has been in impressive form.

โ€œHe is a strong, resilient character and weโ€™re confident he will approach his rehab program with intent and professionalism.โ€

The 24-year-old is enjoying a career-best year at the Hawks, playing all 16 games and averaging 16.5 disposals and 4.9 marks per game.
