West Coast expect captain Luke Shuey to miss between three to four weeks with his latest hamstring setback, but Elliot Yeo is edging closer to a long-awaited AFL return.
Shuey, who has suffered a string of soft tissue injuries over the past two years, injured his hamstring in the final quarter of his team's win over Port Adelaide on Saturday night.
"We're thinking it's a low-grade hamstring but because of the Easter break we haven't quite got the results of the scans as yet," Eagles football manager Craig Vozzo said.
"We'll make plans depending on what those scans say.
"He'll probably be out for at least the next three-to-four weeks we would think, but we'll have a good look at things, get advice from our doctors and come up with a plan to get Luke right for the long-term."
Yeo has been sidelined by osteitis pubis since round 11 last year.
But the 27-year-old has made significant progress in recent weeks and is on track to return before the mid-season bye.
"Elliot joined in with the guys at the captain's run before the game (versus) Port and trained quite well," Vozzo said.
"It was good to see him out there kicking the balls around and not just running around the boundary line.
"I'm sure that was good for him and certainly good for us.
"Having gotten through that section of his build we'll now sit down - our medical staff and (strength and conditioning) staff - and establish a return to play plan now for Elliot, which is exciting."
West Coast will be back in action when they take on St Kilda at Marvel Stadium on Saturday.
