THERE'LL be a close watch on star Collingwood runners Sarah Rowe and Ruby Schleicher after a physical five-point elimination final win over the Western Bulldogs.

If the Pies are to be any chance to defeat Adelaide in their semi-final, the housemates will need to be fully fit.

Rowe spent much of the fourth quarter on the bench with a knee issue, telling physios there was a "pulling" feel as she tried to complete run-throughs, and she didn't see out the game.

Schleicher appeared to suffer an ankle injury halfway through the fourth term, attempting to soccer the ball at a centre bounce and landing awkwardly.

She returned for the frantic final 90 seconds of the game.

Mikala Cann and Tarni Brown have both been initially cleared after receiving head knocks in the fourth term, although delayed concussion can still develop in the days after a match.

"We're not quite sure at the moment, we probably had seven players being assessed in the second half. I know the last quarter, we were juggling around to see who was cleared," Collingwood coach Steve Symonds said.

"I know there were a couple who were assessed for head knocks who were all clear, so that's all good.

"So we've got a couple of bruises, and we just need to see how they come up, really. It's too early to say what they're like, I don't think there's anything that's really bad, we just need to assess it and see where it's at."
