The Boston Bruins placed forwards Anton Blidh and Trent Frederic and goalie Jeremy Swayman in the NHL's COVID-19 protocol on Thursday.
With the number of coronavirus cases and game postponements rising across the league, the addition of Blidh, Frederic and Swayman gave the Bruins six players in the protocol. One team staff member also was placed on the list Thursday.
Patrice Bergeron, leading scorer Brad Marchand and fellow forward Craig Smith went on the protocol list earlier this week. Bergeron entered Wednesday, one day after Marchand and Smith.
