Per a press release from the Club, Mike Commodore has been placed on Injured Reserve retroactive to October 9th.
That basically means Commodore has been unable to play due to his fractured thumb since the Premiere games in Sweden, which we knew.
The key word, however, is retroactive.
Take a look at the NHL's injured reserve rules from the Hockey Operation Guidelines.
Injured Reserve List:
In the event that a player is injured and a Club wishes to place him on the Injured Reserve List the Club must follow these procedures:
A club may place a player on the Injured Reserve List if such player is injured, disabled or ill and unable to perform his duties as a hockey player after having passed the Club's initial physical examination in that season.
A player who has an injury that renders him physically unable to play for a minumum of seven days after that date of the injury can be placed on the Club's Injured Reserve List. Once a player is placed on the list, the Club may replace said player on its NHL roster with another player.
All determinations that a player has suffered an injury warranting injured reserve status must be made by the Club's medical staff and in accordance with the Club's medical standards.
A player placed on Injured Reserve is ineligible to compete in NHL games for a period of not less than seven days.
Players on Injured Reserve may attend Club meetings and meals, travel with the Club and participate in practice sessions.
