West Coast coach John Worsfold has remained tight-lipped on the team he will take into Saturday night's semi-final against Collingwood at the MCG.

The Eagles lost vice-captain Beau Waters (foot) in Sunday's 96-point win over North Melbourne and he will miss the remainder of the season.

Key forward Quentin Lynch was yesterday cleared of a one-week ban for a hit on North Melbourne's Scott McMahon.

Worsfold said Lynch's availability gives the team forward line options.

"We're certainly giving good consideration to how we want to play this week in terms of the structure of our forward line," he said.

"We've got complete faith in that structure. We played with that structure pretty much all last year, night games, wet games, and we know it can work.

"It's a matter of saying, is that exactly the way we want to go this week?"

Collingwood will be without captain Nick Maxwell, who accepted a two-match ban for rough conduct.

Maxwell's absence may tempt West Coast to try and stretch a possibly undersized Magpies defence.

Matt Rosa will train with the main group on Wednesday to stake his claim for a return to the team just three weeks after he broke his collarbone in the Eagles' Round 22 win over Collingwood.

Rosa was on his return from a three-week absence that night because of a broken jaw.

"Today's the big test for him when he trains this afternoon to say whether he's available or not for selection," Worsfold said.

"Then we've got to make a call whether he's played enough football to come in and impact for us.

"That's going to be a tough call, but the first thing he's got to do is get through a pretty rigorous training program today."

Worsfold said there were a number of candidates to replace Waters.

"The guys that have been playing really well in the back half for us, Jacob Brennan, who was the substitute last week, Lewis Stevenson's in outstanding form, and Ash Smith is back up and available now," he said.

"We're really comfortable that we've got those guys ready, as well as Mitch Brown, who makes us a bit taller, but Will Schofield can play a real strong running role as well."
