WEST Coast defender Xavier Ellis could miss multiple weeks with a shoulder injury following a heavy fall in a marking contest in the first-quarter of Sunday's win over Collingwood.
 
Ellis was running back with the flight of the ball when he attempted to spoil a marking contest deep in the Magpies' forward line.
 
His right shoulder hit the ground and he had to be helped from the field, grimacing in pain.
 
The former Hawk was subbed out shortly after and it is likely he could miss a few weeks.
 
"I think it is an AC joint so it is a couple of weeks minimum," Eagles coach Adam Simpson said.

West Coast also lost experienced forward Mark LeCras pre-match due to a tight calf.
 
He was replaced in the side by Dom Sheed, who came on as the sub at quarter-time to replace Ellis.
 
Simpson said LeCras' injury could see him miss the vital clash with Essendon next Saturday.
 
"(His calf) was a bit tight on Thursday," Simpson said.
 
"He wasn't available today and he might not be available next week. (It'll be) touch and go."
 
The Eagles have already lost Matt Rosa, Brad Sheppard, Beau Waters and Sharrod Wellingham for the season.
 
Elliot Yeo has not played since round 13 due to a broken hand and appears unlikely to return this season.
 
Scott Selwood has not played since he had ankle surgery following the Eagles' round 12 loss to Hawthorn. However, although it was initially feared that his season was over he is making a case for a return within a fortnight.
 
"Selwood is pushing hard, really hard to play," Simpson said.
 
"He is running really well but he won't be playing next week."
