WEST Coast is set to add key forward Oscar Allen and midfielder Luke Edwards to its inactive list, ending the season for both and freeing up list spots in preparation for the NAB AFL Mid-Season Rookie Draft.

Allen, who has not played this season, has endured a frustrating battle with a stress-related foot injury that first flared in February, with the young star in and out of a moon boot since.  

Edwards, meanwhile, endured osteitis pubis in the pre-season and has been backed off at training again due to discomfort after playing three games early in his second season.

The pair join prized draftee Campbell Chesser and premiership defender Tom Cole on the Eagles' inactive list, freeing up two more list spots as the club navigates an ongoing player availability crisis.  

"We were holding out a bit of hope for both of them (Allen and Edwards), but it’s just a slow process with their injuries and it’s got to the point now where their recovery marries up towards the end of the season," coach Adam Simpson said.

"It probably makes sense to shut them down and get them right, with no guarantees they were going to get back anyway.

"Both those guys if they got themselves perfectly right we were talking round 21, round 22 at best.

"We’ve taken a cautious approach with those two, but that’s not a green light for us to shut everyone down in round 10. We’re not doing that."

Allen has played 59 games since being drafted with pick No.21 in the 2018 NAB AFL Draft, including 21 last season. 

The 23-year-old is the Eagles' brightest young prospect and seen as a future captain of the club after joining the leadership group ahead of this season.  

Simpson is confident Allen's injury won't drag on long term.

"I don’t think long term we’re in any dangerous territory, but bone stress in your foot is always unforgiving if you don’t get it right," Simpson said.

"It’s just slow. He’s just got out of the (moon) boot. He probably needs another three or four weeks non running, then all of a sudden it’s round 13, 14 before we start the pre-season for him.

"There’s no real time frame when you get to those type of injuries, you just have to let the body take care of it, and it’s just been slow.

"I think we’ll put it down to bad luck at the moment, but we are investigating all those things with the surface, and his boots and orthotics."

Sam Petrevski-Seton became the latest Eagle to enter the health and safety protocols this week.

But West Coast received a dose of much-needed good news when Jamie Cripps' leg infection cleared up much faster than expected.

Cripps was initially ruled out of Sunday's clash with GWS at Giants Stadium, but he will now take Petrevski-Seton's spot in the 22.
