The Ravens made a flurry of roster moves Tuesday afternoon, including adding a pair of big bodies in the trenches.
With safety Terrence Brooks (knee), cornerback Asa Jackson (knee) and running back Lorenzo Taliaferro (foot) heading to injured reserve, Baltimore had three open spots on the 53-man roster.
The Ravens filled two of them by signing defensive tackle Casey Walker off the New England Patriots' practice squad and promoting offensive lineman Ryan Jensen from their own practice squad.
Baltimore still has one open spot.
Walker played in five games, including one start, for New England this season. He made 11 tackles, including one sack.
The 6-foot-1, 335-pound Oklahoma product was originally undrafted in 2013 and signed with the Carolina Panthers. He spent time on their practice squad before the Patriots signed him to their active roster.
Walker adds depth along the interior of the defensive line, which is without Pro Bowler Haloti Ngata for the remainder of the regular season (suspension).
The Ravens also brought Jensen up from the practice squad to provide more depth since guard/tackle Jah Reid was placed on injured reserve last Saturday with a hand injury.
Jensen can play any of the offensive line positions. He's still officially listed as a guard/center but has practiced some at right tackle during training camp, and could be inserted there in a pinch.
The 2013 sixth-round pick didn't see any action during his rookie season. He began the year sidelined by a foot injury and spent the remainder of it practicing with the team as a gameday inactive.
Jensen didn't make the 53-man roster coming out of training camp, but was re-signed to the practice squad. The 6-foot-4, 306-pound Colorado State-Pueblo product told The Baltimore Sun that he was suffering from extreme sleep apnea, which was being treated.
The Ravens could use their final roster spot to add another cornerback after losing two defensive backs Sunday against Jacksonville.
"I don't think you ever feel like you have enough depth to get you through, so we'll be looking at all of our options," Head Coach John Harbaugh said on Monday. "It's one thing to hope to have a guy, and it's another thing to find a guy."
Baltimore filled its two vacant spots on the practice squad by signing defensive end Zach Thompson and cornerback Quinton Pointer.
Thompson has bounced between the New York Jets and Denver Broncos since going undrafted, and has not seen any game action. The 6-foot-5, 265-pounder was a teammate of wide receiver Michael Campanaro's at Wake Forest.
Pointer is in his third season. The former undrafted Nevada-Las Vegas product has played in eight games, last appearing with the St. Louis Rams last season. He was last with the Tampa Bay Buccaneers. The 5-foot-9 cornerback has six career tackles.
