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.
You know what? We've played in some pretty special buildings along this playoff run so far. You start in Detroit, you go to Montreal, you come here … I think it's the first team to beat three Original Six teams to get to the Final if I'm not mistaken. That says how tough the road has been. Those are tough places to win.
