West Coast Eagles forward Liam Ryan will miss Friday’s practice match after entering the AFL’s Health and Safety Protocols, while defender Tom Cole will be sidelined for an extended period due to an ankle cartilage injury.

Ryan is now self-isolating, abiding by government regulations and receiving support from the club.

Cole was injured during a competitive drill at Mineral Resources Park on Tuesday and the 24-year-old will undergo surgery.

“It’s obviously really disappointing for Tom and the club that he has suffered an injury of this nature so close to games starting and after completing a full pre-season up until this point,” Football Manager Gavin Bell said.

“We’ll continue to assess Tom throughout his rehabilitation, but at this stage we expect he will be sidelined for at least the first half of the season.”
