Griffen was placed on the reserve/COVID-19 list Saturday.
Griffen either tested positive for the virus or came into close contact with an infected person. He won't be available for Sunday's game against the Packers, and if he tested positive, he'll miss next week's game versus the Titans as well. Romeo Okwara, Da'Shawn Hand (groin) and Austin Bryant (thigh) will handle most of the reps at defensive end in Week 14.
