COLLINGWOOD'S depth will be tested even further over the next two weeks, with captain Brianna Davey to miss at least two games due to concussion and midfielder Mikala Cann banned for one.

Davey collided with West Coast's Ella Roberts in a marking contest during the second quarter of Tuesday night's loss to the Eagles and took no further part in the match.

She subsequently entered the competition's 12-day concussion protocols, making the earliest she can play again September 30.

The Pies play the Western Bulldogs on Sunday, September 22, and Gold Coast on Friday, September 27, meaning Davey will miss at least both of those games.

Notwithstanding any complications or persistent symptoms in her recovery, she will next be available for selection for the Pies' match against Richmond on Saturday, October 5.

"She'll miss the next two games which is really disappointing for her, first and foremost," coach Sam Wright said after Tuesday night's match.

"But she's OK, and that's the most important thing.

"I think for us as a club, any time you lose a player and a leader like that, is really hard to come back from but I'm more disappointed for Bri because she's put in so much work."

MEDICAL ROOM The complete AFLW injury list

Cann will also miss the game against the Bulldogs after copping a one-match ban for rough conduct on Eagle Isabella Lewis.

The double blow is more bad news for the Pies, who have already had to play a VFLW top-up player twice this season as they'd dipped below 24 available listed players.

They currently have seven players on their injury list, with only West Coast (nine) and Melbourne (eight) having more.

Some respite will come in the form of midfielder Tarni White being available for selection for Sunday's match against the Bulldogs after serving her three-match suspension.
