The league has not had a positive test since July 13-17 testing, which was during the training camp period of its return to play. No players have tested positive since the NHL entered its two hub cities, where players are sequestered from the general public.
By all accounts, every league that has put together a so-called bubble has found success. The NBA and WNBA have not had a player test positive for COVID-19 since entering their respective bubbles, and MLS held its MLS Is Back tournament successfully after FC Dallas and Nashville SC withdrew from the event following outbreaks. MLS avoided positive tests once play got underway. Likewise, the NWSL successfully held the Challenge Cup in Utah with only the Orlando Pride dropping out as a result of an outbreak ahead of the tournament.
Major League Baseball, which does not have a bubble format, has had several outbreaks that have threatened its season. The St. Louis Cardinals have been limited to just five games in 2020 after the club had an outbreak.
The NHL held a 24-team playoff system after ending its regular season, with qualifying games taking place over the last two weeks. The standard 16-team playoff is set to begin this week.
