Collingwood have listed star duo Ruby Schleicher and Sarah Rowe as tests ahead of Saturday's semi-final against Adelaide as the pair nurse knee injuries.

Both suffered setbacks in last Sunday's thrilling win over the Western Bulldogs, where Schleicher returned from a previous knee issue.

After suffering further damage to her knee late into the five-point win, Schleicher will require further assessment in the days leading up to their clash with the Crows at Unley Oval.

Rowe is also set to undergo testing in the coming days top prove her fitness for the must-win match, having also suffered a knee injury against the Dogs.

Collingwood confirmed on Wednesday afternoon that the pair are no certainty to line up against Adelaide as the two clubs fight for a preliminary final berth against Brisbane.

In brighter news for the Magpies, young gun Tarni Brown has passed a required concussion test after suffering a head knock against the Bulldogs, while Erica Fowler will also be in the selection frame after recovering from concussion.

Schleicher was among a trio of conclusions for her side's elimination final last week, with Alison Downie and  Abbi Moloney also added to the 21-person side.

Emily Smith, Alana Porter and Jordan Membrey were omitted for the match and will be in contention for a recall should Schleicher and/or Rowe be deemed unfit to play.

Saturday's semi-final will commence at 3:40pm (AEDT) at Unley Oval on Saturday afternoon.
