The NHL says only two players tested positive for COVID-19 during the first five days of training camp last week.
The league, in consultation with its players, is not revealing the identity of players who test positive, or their teams. The two players who tested positive are self-isolating per national and local health protocols.
A total of 2,618 tests of more than 800 players from July 13-17 were done by the league. Training camps opened July 13, with 24 teams preparing to compete in an expanded playoff format in Toronto and Edmonton, Alberta, starting on Aug. 1.
Teams are scheduled to travel to both hub cities on Sunday.
The NHL reported it had 33 players test positive during the period after the league paused its season in March to the start of camps.
