Adelaide star Eddie Betts has been ruled out of Sunday's clash with Collingwood due to appendicitis.

The 30-year-old was admitted to hospital last and had surgery to remove his appendix.

โ€œEddie fell unwell on Sunday evening and was sent to hospital,โ€ Adelaide senior medial officer Dr Marc Cesana said.

โ€œHe will not play this weekend as he recovers from surgery and the Club will continue to monitor his health before a decision is made on his availability.โ€

The Magpies host the Crows at the MCG on Sunday afternoon.
