HABS EUROPE GAME?
In a visit to the Bell Centre, NHL commissioner Gary Bettman expressed interest in the Montreal Canadiens playing a game in Europe.
“There's a real appetite to take the Montreal Canadiens abroad,” Bettman said. “But it's got to be the right circumstances, the right market and the cost element is something we have to deal with but it's something that I believe is on the horizon.
“I'd very much like to take the Canadiens to Europe.”
Bettman added that Canadiens owner Goeff Molson is co-chairman of the league’s international committee.
The NHL’s 2022 Global Series saw games played in Germany, Finland, Switzerland and Czechia at the start of the 2022-23 season.
The Canadiens will cap off a five-game home stand on Thursday against the Detroit Red Wings.
The Bruins continue their road trip with a visit to the Tampa Bay Lightning on Thursday.
