Cook isn't expected to play Sunday against the Broncos after the Chargers placed him on the reserve/COVID-19 list Friday following a positive test for the virus, Mike Garafolo of NFL Network reports.
Even if vaccinated, Cook will have a minimal chance to clear the NFL's COVID-19 return-to-play protocol before Sunday's 4:05 p.m. ET kickoff, so the Chargers and fantasy managers alike should proceed as though he won't be available Week 17. He's one of 10 members of Los Angeles' 53-man roster that is on the list as Sunday's game approaches, though the Chargers at least received some reinforcement for the passing attack when wideouts Mike Williams and Jalen Guyton were activated from the list earlier this week. With Cook's top backup for most of the season, Donald Parham (concussion), on injured reserve, the Chargers likely will turn to Stephen Anderson and Tre' McKitty to pick up the snaps at tight end this weekend.
