HAWTHORN captain Luke Hodge will this week undergo surgery on the knee he injured early in the year.
Hodge damaged the posterior cruciate ligament in his left knee against St Kilda in round six, missing several weeks.
Hawthorn football manager Mark Evans said, depending on how the surgery went, the skipper would be back running by December.
Shaun Burgoyne and Jarryd Roughead have had ankle problems which also require post-season surgery, while Jordan Lewis has already had some shoulder damage repaired.
"He's going into hospital next week for an operation to do with his PCL. It needs some stablisation and they'll have a look at it while they're in there and do a bit of a clean-out," said Evans of Hodge.
"He should be running before the end of the year, so he'll just need to take it a little bit slowly. We don't start pre-season until late November, so he'll just be a few weeks behind the rest of the group.
"He's fine, but the knee's not quite as stable as it could be."
