Eller was removed from the ice on a stretcher during the second period of Game 1 of the Canadiens' Eastern Conference Quarterfinal series against the Ottawa Senators after he was hit by Ottawa's Eric Gryba.
The team announced Thursday that Eller had been hospitalized after sustaining a concussion, facial fractures, loss of consciousness and had teeth knocked out after the hit and falling face-first to the ice.
It is really special. I had a lot of friends and family here tonight, and for my first [NHL] game in here it was great. I played here as an elementary-school player in the city championships and this was my first time back. It was a lot of fun.
