Key defender Zaine Cordy has been ruled out of Sunday’s match against the Adelaide Crows due to injury.

The 23-year-old picked up a chest muscle injury at training earlier this week.

“Scans have revealed a low-grade strain for Zaine,” medical services manager, Chris Bell, said.

“At this stage, we will look to manage the injury conservatively and anticipate this will sideline Zaine for between two and four weeks.”
