The Montreal Victoire went down a forward on Thursday night.
Maureen Murphy exited against the Seattle Torrent due to an upper-body injury and did not return.
She suffered the injury following a big hit from Torrent's forward Theresa Schafzahl that sent her into the boards.
Murphy has totalled four goals and three assists in 19 games played this season.
The Victoire are also without captain Marie-Philip Poulin, who was injured on Sunday against the Boston Fleet.
