Baltimore tight end Mark Andrews has reportedly tested positive for COVID-19, making him the latest member of the Ravens roster to be ruled out of Tuesday's game against the Pittsburgh Steelers.

The AFC North rivals were initially due to meet on Thursday as part of the Thanksgiving schedule, only for the NFL to move the game to Sunday amid a coronavirus outbreak in the Ravens camp.

The divisional contest was then pushed back again as Baltimore continued to move players to the reserve/COVID-19 list, among them starting quarterback and reigning NFL MVP Lamar Jackson.

On Saturday, it was announced six more - Jaylon Ferguson, D.J. Fluker, Broderick Washington, Will Holden, Khalil Dorsey and Tavon Young – had been added, taking the tally this week to 18.

The Baltimore Sun and NFL insiders reported Andrews' positive test early on Sunday, with defensive end Matt Judon then also ruled out due to the NFL's protocols during the health pandemic.

Andrews has 38 receptions for 454 yards and six touchdown catches this season, leading the way in all three categories for his team.

With so many absentees, the Ravens – who have lost three of their previous four outings to slip to 6-4 for the season - have signed Dez Bryant to their 53-man roster.

The veteran wide receiver had already played in two games this season, recording four catches for 28 yards last Sunday in the overtime loss to the Tennessee Titans.

Pittsburgh - who go into the Week 12 game at Heinz Field with a 10-0 record - are also facing the prospect of playing without some key starters, albeit not to the same extent as their opponents.

James Conner was moved to the reserve/COVID-19 list by the Steelers on Saturday, joining defensive end Stephon Tuitt, defensive tackle Isaiah Buggs, and offensive tackle Jerald Hawkins.
