Yesterday was the opening of training camps around the NHL, and all eyes were on the rosters to see who was where, who was hurt, and who was mysteriously absent.
William Nylander revealed he has not been fully vaccinated yet:
William Nylander is doing his media availability in a mask because he's not fully vaccinated yet. Says he'll be fully vaxxed before the season.— Chris Johnston (@reporterchris) September 22, 2021
The NHL is not requiring players to be vaccinated, but they are subject to suspension without pay (which provides the team with cap relief) if they cannot do things like go on road trips or cross the border.
