Collingwood duo Mason Cox and Dayne Beams have been ruled out for the rest of the 2019 season.

Cox will have surgery later this week after tearing a retina in his eye in Sunday's win over the Gold Coast.

โ€œMason has been advised that after the surgery he will need a number of weeks rest which means that he will not play again this season,โ€ Collingwood GM of Football, Geoff Walsh told the club website.

โ€œYou donโ€™t take risks with situations like this. A second appointment with a specialist this morning confirmed that Mason suffered a tear to his retina that needs surgical repair.

โ€œIt is obviously a disappointment, especially for Mason, but importantly he is expected to make a complete recovery. We look forward to his return to the club.โ€

Beams has undergone shoulder surgery that was originally scheduled for post-season. It was brought forward to ensure he is right to go for the 2020 pre-season.

The star midfielder has endured a tough 2019 campaign, undergoing hip surgery in June before taking a leave from football to address his mental health.
