Essendon duo Cale Hooker and David Zaharakis have both endured injury setbacks.

After undergoing post-season surgery on his hip, Hooker is still experiencing some discomfort.

โ€œCale finished the season with some hip pain. We felt that with an extended period of rest over the off-season, this pain would go,โ€ Bombers head of medical services David Rundle toldย essendonfc.com.au.

โ€œBut unfortunately, after a few weeks of running, the hip pain was still there and probably getting a bit worse.

โ€œWe sought specialist opinion and he underwent an arthroscopy yesterday โ€“ a relatively minor procedure โ€“ and we should see him back up and running in the new year.โ€

Zaharakis is set to undergo surgery on Thursday to repair a minor torn meniscus in his right knee.

โ€œDavid had ankle surgery in the off-season, he was rehabilitating really well following that and his ankle was feeling great," Rundle said.

โ€œUnfortunately, after a couple of weeks of running, his right knee had some swelling and clicking in it and he was found to have a small meniscus tear. Heโ€™s undergoing an arthroscopy today.โ€

Bombers youngster Noah Gown has also re-fractured a bone in his foot and is seeking further advice from a specialist on Friday.
