Details about Boeser's injury have not been disclosed. On Oct. 1, head coach Travis Green declared Boeser would miss "about a week" and he returned to the ice Oct. 9. The Canucks will need to designate someone off their 23-man roster before activating Boeser.
He had 23 goals and 49 points in 56 games last season.
In other Canucks news, Brady Keeper (leg fracture), Tyler Motte (upper-body surgery) and Brandon Sutter (long-term COVID-19 symptoms) were also placed on injured reserve.
The team opens the regular season on Wednesday in Edmonton against the Oilers. Below is the Canucks' initial 23-man active roster for the 2021-22 campaign.
