Packers star receiver Davante Adams has been placed on the reserve/COVID-19 list, the team announced Monday.

The announcement comes as a huge blow to Green Bay (6-1), who are getting set for a heavyweight collision with the Cardinals (7-0) on Thursday night at 8:20 p.m. on FOX. Adams, 28, is arguably the best receiver in the NFL, racking up 744 yards on 52 receptions with three touchdowns this season.

With a short week ahead, the Packers have now moved into enhanced mitigation COVID protocols. That includes daily testing and required masking for all at the Packers facility, regardless of vaccination status. Adams doesn’t have much time to get off the list, meaning he will likely be out on Thursday night.

In his absence, quarterback Aaron Rodgers will lean on Allen Lazard, Randall Cobb and Robert Tonyan in the passing game. Running back Aaron Jones figures to see more opportunities as well, a role he’s accustomed to.
