San Francisco 49ers wide receiver Brandon Aiyuk has been placed on the team’s COVID list. He’ll need to test negative for the virus time days in a row to be cleared to return to the field. With San Fran on a bye this week, there’s still plenty of time for Aiyuk to be back for a Week 12 meeting with the Rams, so it’s probably too early to start thinking about contingency plans if you have the talented rookie on your roster.
