Geoffrion, the grandson of former Canadiens star Bernie Geoffrion and great-grandson of Howie Morenz, left the game due to lingering effects of a skull fracture and concussion sustained during an American Hockey League game in November.
He was selected by Nashville in the second round of the 2006 draft and had eight goals and five assists in 55 career NHL games with the Predators and Montreal.
The Blue Jackets also announced that former NHL defenceman Bob Halkidis has been added to the team's scouting staff.
This is a big year for us in a lot of ways. You can see Garth and management really trying to find that solution to get us into the playoffs and consistently have that. The pressure is great. You have to enjoy it. It just means there's a great opportunity ahead of you.
