The St. Louis Blues placed captain Ryan O'Reilly and forward Brandon Saad on the club's non-roster COVID-19 protocols list Tuesday.
O'Reilly will miss at least 10 days, while Saad won't likely be out that long, Blues head coach Craig Berube said, according to Jim Thomas of the Post-Dispatch.
St. Louis recalled center Dakota Joshua from its AHL affiliate, the Springfield Falcons, in a corresponding move.
O'Reilly has produced two goals and three assists over five games this season. The 30-year-old leads all Blues forwards in average ice time with 19:13.
Saad, who'll turn 29 on Wednesday, has collected a goal and an assist in three contests this campaign. The Blues signed him to a five-year contract as a free agent in July.
