Running backs Mark Ingram and J.K. Dobbins, defensive lineman Brandon Williams, linebacker Pernell McPhee, defensive end Calais Campbell, and offensive linemen Patrick Mekari and Matt Skura were all placed on the reserve/COVID-19 list in the week leading up to the AFC North showdown with Pittsburgh.

Baltimore is 6-4 and four games behind the 10-0 Steelers in the AFC North. It is also behind the 7-3 Cleveland Browns in the division.
