The Ravens made a flurry of roster moves Tuesday morning after season-ending injuries to Pro Bowl guard Marshal Yanda (ankle) and rookie linebacker Bam Bradley (knee).
With Yanda and Bradley officially going to injured reserve (IR), it puts the Ravens at 15 players on IR two weeks in the season.
With the two open spots on the 53-man roster, the Ravens promoted center Matt Skura from the practice squad and signed offensive tackle Dieugot Joseph off the Chicago Bears practice squad.
Joseph is an undrafted rookie out of Florida International.
