"He just notified our GM that he's considering retiring," Dominick Saillant, the Canadiens' director of media relations, told CBC Hamilton.
However, Geoffrion has not officially retired, Saillant said. The 25-year-old player has not filed the necessary paper work or made a formal announcement.
On Wednesday afternoon, Hamilton Bulldogs spokesman Derek Wills said "we're not going to be commenting at this point in time until we have more information."
Considered a top prospect for the Habs, Geoffrion suffered a skull fracture during a Bulldogs game at the Bell Centre in Montreal against the Syracuse Crunch. After a hip-check from Syracuse's Jean-Phillipe Côté, Blake's body flipped and his head hit Côté's skate.
Days later, Geoffrion underwent skull surgery in Montreal to repair the damage.
After the surgery, when it became clear Geoffrion would recover, his father, former NHL player Danny Geoffrion, told CBC News that doctors had made several life-saving decisions and that he expected his son to make a full recovery.
"If it wasn't for a couple of quick calls that the trainer and the doctor made there on the spot to get him into the ambulance and into the hospital, Blake could not have been here with us today or have severe brain damage."
The younger Geoffrion played 13 games for Canadiens last season, scoring two goals.
