On Thursday, defenceman Nikita Zaitsev was placed by the Senators into the NHL's COVID-19 protocol, the third Ottawa player to be added to the list in one day.
Alex Formenton and goaltender Matt Murray were added to the COVID-19 list by the Senators earlier in the day. A total of nine Ottawa players were in the protocol when the Senators hosted the Los Angeles Kings on Thursday night.
And on Saturday night, the Senators lost centre Shane Pinto in his first game back from the injured reserve list. Pinto was suspected of having injured his right shoulder.
