(Undated) -- The NBA is warning unvaccinated players that they soon won't be able to play games in Toronto. ESPN obtained a memo from the league that warns teams that unvaccinated players won't be allowed to travel to Canada starting on January 15th due to a new Canadian law. It also stated that unvaccinated players who leave the country with a temporary VISA status won't be allowed to re-enter the United States. Teams will also have to report which players remain unvaccinated to the league office by Friday.
