We have been in touch with and are working with the League to address these discrepancies with additional testing and expect to have further information later this afternoon. The League will provide a further update when we have more information. Head Coach Craig Berube and our players will not be available to the media until after tonight’s game."

ESPN's Greg Wyshynski explained on Friday that the NHL wants that situation resolved by June 1. "The conversations are ongoing," NHL chief content officer Steve Mayer told ESPN on Friday. "We've told them we really do need to know by the end of the first round, and that's around June 1. That's pretty much the date that we've talked to them about, saying we have to know one way or another." As things stand today, the remaining Canadian club would likely relocate to a U.S. city close to its opponent for the semifinal matchup to limit travel costs. Mayer added, though, that government officials may be more open to personnel traveling between the countries after two Canadian teams are eliminated in the tournament's first round.

Both teams are out of the playoff race and will finish the year with a pair of afternoon tilts.

The other three divisions will already be well into their first-round playoff matchups. Things kick off on Saturday with the Washington Capitals hosting the Boston Bruins. As for the future, the league is expected to go back to the schedule matrix and playoff format that was used during the 2018-19 season, according to Nick Cotsonika of NHL.com, with the exception of course of the Seattle Kraken being added to the Pacific Division and the Arizona Coyotes moving to the Central.

Specifically, if players break protocols that lead to multiple illnesses during the playoffs, there could be huge consequences. Essentially, if a player(s) breaks the rules when it comes to COVID protocols and it costs their team a number of players because the virus spreads, the NHL won’t first look to reschedule games. Instead, they’ll look at why the breakout and spread of the virus occurred and the team could be penalized by having to pull out of the NHL postseason.
