The Calgary Flames, who have already had three games postponed amid a COVID-19 outbreak, added coach Darryl Sutter and 16 other team members to the league's protocols on Wednesday.

The team said it added seven players, three coaches and seven support staff members to the list. The moves come after six players and another staff member were entered in the protocol on Monday.

The players entering protocol on Wednesday include Rasmus Andersson, Byron Froese, Johnny Gaudreau, Erik Gudbranson, Trevor Lewis, Jacob Markstrom and Tyler Pitlick.

Along with Sutter, associate coach Kirk Muller and assistant Ryan Huska also are in the protocol.

Games against Chicago (Monday) and Nashville (Tuesday) had already been postponed, with Thursday's game against Toronto also called off.

The games were postponed because of concern about continued spread and the likelihood of additional positive cases, the league said in a news release. The Flames' training facilities have been closed until further notice.
