THE PROVINCE: Seven more Vancouver Canucks players were added to the NHL COVID-19 protocol list on Saturday while two more coaches also tested positive. Travis Boyd, Thatcher Demko, Jayce Hawryluk, Bo Horvat, Tyler Myers and Brandon Sutter were the new additions to the list. Several of the cases affecting the club are the highly contagious Brazilian P.1 variant.

Hawryluk is a positive case, marking the second time in a year he’s tested positive for COVID-19. Research shows the P.1 variant is capable of reinfecting people who previously suffered from other strains of the coronavirus.

TSN: Pierre LeBrun reports the NHL is proceeding on the assumption the entire Canucks team will likely test positive. It’s built into the league’s planning going forward, similar to what happened at the start of the season with the Dallas Stars. This is a variant of the coronavirus the league hasn’t seen before.

The Canucks shutdown will last longer than anticipated. They will not be playing next week. The league has discussed future dates with the club but those won’t be announced for a while.

North Division games will likely be scheduled past May 11, using the week of May 10-14 as a buffer. The three US divisions could still start their playoffs on May 11. The league also remains confident it can complete the 56-game schedule.

SPORTSNET: Elliotte Friedman reports there are discussions about holding the 2021 Stanley Cup playoffs in a bubble environment similar to last year, though it’s not something anyone wants at this point. Much will depend upon how things evolve between now and then.

Meanwhile, the NHL has issued a memo to its 31 teams reiterating the rules, regulations and best practices for mitigating the spread of COVID-19.

SPECTOR’S NOTE: Previous outbreaks among several clubs have put a strain on the schedule, with most teams facing a grueling timetable over the next six weeks making up games postponed earlier in the season. That’s going to take a physical toll on the players over the next month.

The league wants to avoid moving the regular season and playoff schedules forward because they don’t want to push the postseason any deeper into the summer than it already is. They also don’t to risk the Stanley Cup Final being staged at the same time as the 2021 Tokyo Olympics, which are slated to begin on July 23.

Teams want to avoid a playoff bubble because it will adversely affect their already depleted revenue for this season. The players don’t want it because they’ll be separated for weeks from their families. Nevertheless, they could have little choice if the variants of the coronavirus lead to a significant increase in infections among the North American population.
