The NHL hockey league on Tuesday announced that 27 league players were diagnosed with coronavirus infection during training camps.
Infections were found in less than two weeks from nine different clubs, the NHL said on its website.
The worst virus has hit the Finnish-filled Dallas Stars team, where the infection was detected in 17 players.
Stars returned to practice on Tuesday after the corona quarantine, but there were still 14 players on the sidelines.
Of the Finnish players, Miro Heiskanen, Julius Honka, Joel Kiviranta and Esa Lindell did not participate in the exercises.
The first three matches of the Dallas season have been canceled.
The stars can start their season at their earliest on January 19 against their final opponent Tampa Bay last fall.
- We don't know if we can play then or not.
That would give us six exercises, starting on January 22 with eight exercises.
We have a lot of work to do.
Today was a good day because we weren’t on the ice for five days, Dallas head coach Rick Bowness said.
The NHL will start Finnish time on the night before Thursday in a five-match round.
