Crows captain Rory Sloane has been ruled out of Sunday’s game against North Melbourne due to an eye injury.

Sloane, who consulted with a specialist on Friday afternoon, reported blurred vision during training on Thursday and now requires surgery to remedy a retinal detachment.

Crows Head of Football Adam Kelly said the corrective procedure would ensure the 31-year-old made a full recovery.

“Rory’s health and wellbeing is obviously our number one priority,” Kelly said.

“At this stage, it is hard to give a definitive date on when he will return to the field but we are hopeful of it being in the vicinity of 2-4 weeks.”
