Placement on the list means Stafford has had close contact with someone who has contracted the novel coronavirus or he has tested positive for COVID-19, which teams do not divulge.
The second National Football League quarterback placed on the reserve/COVID-19 list after the Falcons' Danny Etling, Stafford is the initial starting quarterback to be placed.
Stafford's status will be one to monitor moving forward.
The NFL and NFLPA have agreed on a policy that states "clubs are not permitted to comment on a player's medical status other than referring to roster status". Stafford is entering his 12th season with Detroit after being drafted by the Lions with the No. 1 overall pick in 2009. His wife, Kelly, had brain surgery in 2019 as well. Hockenson also hit the reserve group earlier this week.
Stafford played every game for the Lions from 2011-18, but back and hip injuries caught up with him and he missed half of last season. Jacksonville defensive end Lerentee McCray went on the reserve/opt-out list too.
