OWINGS MILLS, Md. -- The Baltimore Ravens continue to make moves to help an offensive line that has been hurt by injuries all year.

The Ravens promoted center/guard Matt Skura from their practice squad and signed offensive tackle Dieugot Joseph off the Chicago Bears' practice squad. They take the roster spots of Pro Bowl guard Marshal Yanda (ankle) and inside linebacker Bam Bradley (ACL), both of whom were placed on injured reserve.

Skura, 24, started all four preseason games for the Ravens this season, and it looked like he was going to make the 53-man roster before Baltimore traded for offensive linemen Tony Bergstrom and Luke Bowanko. The Ravens added Skura to the practice squad for the second straight year, and he could be active Sunday against the Jacksonville Jaguars as a backup for the interior of the line.

Joseph, 23, is an undrafted rookie out of Florida International who can play both right and left tackle. At 6-foot-6, 293 pounds, Joseph has great length and a strong lower body but needs to improve his technique.

The offensive line has lost four players since the start of training camp in late July: Yanda, starting left guard Alex Lewis (shoulder), center John Urschel (retirement) and rookie fourth-round pick Nico Siragusa (knee).

The Ravens put three players on the practice squad, re-signing running back Jeremy Langford and adding guard Arie Kouandjio and linebacker Nicholas Grigsby.
