The NHL announced Friday that 11 players have tested positive for COVID-19 since the league began Phase 2 of its return-to-play plan on June 8.
All players who tested positive have self-isolated and followed health protocols, the league said.
Over 200 players have been using team training facilities in groups of up to six on a voluntary basis during the second phase of the league's restart plan. All players taking part in voluntary activities have been subject to mandatory testing.
The Tampa Bay Lightning disclosed earlier Friday that they have temporarily closed their facilities after three players and additional staff tested positive for the coronavirus. Toronto Maple Leafs star Auston Matthews has reportedly tested positive.
The league added it will provide weekly updates detailing the number of tests administered and the aggregate results of those tests as it works to resume its season. The identities of players and the clubs for which they play will not be disclosed.
