CKAC is saying at least a month for each: http://tsn.ca/nhl/story/?id=350130

Cammalleri has a separated shoulder.

Pacioretty has a fractured/bruised set of ribs. Even just one bruised rib will slow you down, a broken one will mean nothing but rest until it's had time to heal.

Just brutal losses for this team already missing its best two defencemen.

People are clamouring for Maxim Lapierre and Ryan O'Byrne...as if either one of those two, or both combined, makes up for the loss of one of our top four players.

The next month--possibly more, possibly less--is going to be a real struggle. As so much of this year has, the fate of the Canadiens will be decided between the pipes.
