Cardinals' Tanner Vallejo: Enters COVID protocols

Vallejo was placed on the reserve/COVID-19 list Tuesday, Darren Urban of the Cardinals' official site reports. This was the result of testing positive for the virus, according to Ian Rapoport of NFL Network.

Vallejo returned Sunday against Dallas after a six-week absence due to a knee injury. Now Vallejo is in danger of missing the Cardinals' Week 18 matchup with the Seahawks. When healthy he has provided depth at linebacker and worked on special teams, roles to which he'll work to return, if he can clear protocols in time.
