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.
