The International Olympic Committee says that any confirmed positive COVID-19 case at the Olympic Games must produce two negative tests 24 hours apart. Otherwise, the quarantine period can last from 21 days up to five weeks in accordance with Chinese law.
According to TSN Hockey Insider Chris Johnston, this could be problematic for NHL players should they attend the Beijing Winter Olympics next February. A call between the IOC, IIHF, NHL and NHL Players' Association is expected soon to review these matters.
