The Baltimore Ravens announced that veteran outside linebacker Justin Houston was placed on the reserve/COVID-19 list on Monday.
Houston, 33, becomes the sixth player from the team's 53-man roster to be placed on the list, leaving his status for Sunday's Week 16 game against the Cincinnati Bengals in jeopardy.
In thirteen games the pass rusher has played in this season, Houston has notched 4.5 sacks - third-most on the team - one forced fumble, 29 combined tackles and 17 quarterback hits.
If Houston is unable to suit up on Sunday, the Ravens may look to rely on outside linebacker Pernell McPhee, who was activated from injured reserve to the 53-man roster on Monday.
