Geelong skipper Joel Selwood fill face a delayed start to pre-season after undergoing hamstring surgery earlier this month, reportsย The Herald Sun.

The 31-year old is not expected to return to training until at least January.

โ€œMy pre-season will be staggered again and I will be looking to join back in with the group in January,โ€ Selwood toldย The Herald Sun.

โ€œI had a minor hamstring operation a couple of weeks ago so I will just make sure that I get that right and then go from there.

โ€œSo before Christmas I will be limited in what I do but I will be working behind the scenes.โ€

Selwood battled a knee issue last summer before playing a new role on the wing for Chris Scott's side in 2019, averaging 21.3 disposals from his 23 games.

While the majority of his teammates will return for pre-season next Monday, Selwood won't feature until the new year.

The veteran said the Cats know they must stay hungry and improve from a campaign where they claimed the minor premiership but bowed out to Richmond in the preliminary final.

โ€œWe know we need to improve again,โ€ he said.

โ€œWe improved last year, we were hungry to improve, so we have to make sure that hunger is still there to get to that next stage. We got to a stage where we were thereabouts and played some really good footy against some good sides but at the end of the day we didnโ€™t finish up how we wanted.

โ€œThe hunger is the big one, and how we sue that energy throughout whole pre-season to make sure in the lead up to Round 1 we are ready to go again. It will be pretty similar and we thought we had a pretty solid pre-season last year so we will try to get as many numbers on the track as possible โ€ฆ and then from there it is just making sure we are working at getting better.โ€
