Ravens place Taliaferro on IR, sign former Patriots defensive tackle Walker

The Ravens officially sent three players to injured reserve on Tuesday with rookie running back Lorenzo Taliaferro joining injured defensive backs Asa Jackson and Terrence Brooks.
Head coach John Harbaugh had already confirmed Jackson and Brooks would miss the rest of the season, but the news of Taliaferro’s status is disappointing after he rushed for 292 yards and four touchdowns on 68 carries, often serving as the primary backup behind starter Justin Forsett. Taliaferro suffered a foot injury in the Week 14 win over Miami and missed this past Sunday’s game against Jacksonville after the Ravens promoted rookie running back Fitz Toussaint from the practice squad.
Taliaferro had originally been described as “day-to-day” by Harbaugh on Dec. 8.
To fill two of the three spots vacated on the 53-man roster, Baltimore promoted offensive lineman and 2013 sixth-round pick Ryan Jensen from the practice squad and signed defensive tackle Casey Walker away from New England’s practice squad. Walker appeared in five games for the Patriots earlier this season, collecting 11 tackles and a sack.
The 6-foot-1, 335-pound undrafted free agent out of Oklahoma started his career with the Carolina Panthers in 2013 before he was signed by the Patriots in late September of this season. He had been on New England’s active roster until late last month when he was waived to make room for running back LeGarrette Blount and then re-signed to the practice squad.
Jensen spent his entire rookie season on the 53-man roster without appearing in a game, but the Colorado State-Pueblo product did not make the team at the end of the 2014 preseason, agreeing to join the practice squad after being waived.
As of Tuesday afternoon, one spot had yet to be filled with many expecting the Ravens to add a defensive back in the wake of the season-ending injuries to Jackson and Brooks.
With Jensen and Toussaint promoted in recent days, the Ravens signed defensive end Zach Thompson and cornerback Quinton Pointer to the practice squad. Thompson is a Wake Forest product and previously spent time with the New York Jets and the Denver Broncos.
Pointer is in his third NFL season and appeared in eight games with the St. Louis Rams in 2012 and 2013. He was most recently with the Tampa Bay Buccaneers.
