Canucks coach Travis Green said Saturday prior to a game in Buffalo that Boeser is week to week. Green says the 21-year-old forward "will be fine" after a period of rest.
Boeser returned to Vancouver on Thursday to see a specialist. The Canucks play their next four games on the road before returning home Nov. 17 to face the Montreal Canadiens.
Boeser finished second last season in voting for the Calder Trophy, the NHL’s award for the top first-year player. He has four goals and seven assists in 13 games this season.
