With Buck Pierce's status still uncertain, the Winnipeg Blue Bombers are preparing a game plan without knowing who their starting pivot will be Monday in Montreal.

Pierce has a mild concussion but could be cleared to play.

If he doesn't, Joey Elliott will take the snaps and both men were on the field for practice Wednesday.

Offensive co-ordinator Gary Crowton says he's preparing game plans for both but he's hoping Pierce is ready to play.

Pierce has said he feels fine but he has to pass a test before he's allowed to return.

He was injured by a helmet to the chin in Saturday's 29-10 loss to the Toronto Argonauts.
