Coyne will have surgery next week and may struggle to return before the end of the season..

“Obviously it’s a huge blow and an injury we didn’t need,” Perth Glory coach Ian Ferguson said.

“With Scott Neville already out and Steve Pantelidis still a few weeks away from match fitness, it leaves us short at the back.

“Chris is a big character and leader, a player we will miss.”

Coyne picked up the injury late in the game against Melbourne Victory on November 20.
