As a result, Nate Stanley and Kirk Cousins, both considered high-risk close contact, will not be able to practice Saturday and must adhere to a five-day quarantine prior to returning to training camp.The protocols created this summer by the NFL players' union indicate that high-risk close contacts are considered to be ineligible for vaccinating a player.According to Mike Zimmer, Vikings coach, Jake Browning is fully vaccinated and will be Minnesota's quarterback for Saturday's practice.Zimmer didn't specify how many players would need to be absent from Saturday's practice or if any would be placed on the COVID-19 reserve roster. However, the Vikings coach stated that the team had not considered cancelling the practice.Zimmer stated, "You know, quite frankly, after all we went through last year. I'm certainly not surprised at all." "I'm disappointed that this happened. I am frustrated. Not just with my football team who were not vaccinated but with everyone else. We will do our best. It's disappointing."
