The Ravens have signed veteran defensive tackle Justin Ellis, as Ian Rapoport of NFL.com reports (via Twitter). Ellis was a regular member of the Raiders’ D-line since Oakland selected him in the fourth round of the 2014 draft, and he even landed a three-year, $15MM contract with the Silver-and-Black in March 2018. But his 2018 season was marred by injury, and he was released with an injury settlement in October.

And while Baltimore scored its fifth straight win on Sunday, its defensive front was noticeably shaky, perhaps because starting DT Michael Pierce played just three snaps. Pierce exited the game against the Bengals with an ankle injury, and head coach John Harbaugh said that an MRI didn’t reveal any long-term concerns. But as Jeff Zrebic of The Athletic writes, Harbaugh was non-committal as to whether Pierce would be available for this Sunday’s crucial matchup with the Texans, instead calling Pierce’s status “day-to-day.”

In addition to Ellis, the Ravens are adding another free agent DT, Domata Peko, as Zrebiec tweets. The Ravens, who are intimately familiar with the long-time Bengal’s work, attempted to sign him earlier this season, but the two sides were unable to agree on terms at the time. Tom Pelissero of the NFL Network reports that Baltimore will pay Peko $1MM for the remainder of the season (Twitter link).

Neither Ellis nor Peko are likely to create much of a pass rush in the interior of the line — which Baltimore could really use — but like the Ravens’ earlier additions of linebackers Josh Bynes and L.J. Fort, both are experienced veterans who understand their assignments and who should, if nothing else, solidify the run defense. That will be essential given Pierce’s uncertain health and the fact that the Ravens are putting rookie DT Daylon Mack on injured reserve, per Zrebiec.

Baltimore, at 7-2 and in first place in AFC North, is doing everything it can to keep the second-place Steelers at bay while pushing for a postseason bye. Zrebiec says the club is expected to add rookie CB Iman Marshall to the active roster this week, and given that the Ravens’ kickoff and punt coverage teams have been uncharacteristically unsteady, Marshall may be asked to bolster those units.

In a corresponding move, the Ravens have waived return man Cyrus Jones, per Zrebiec. Jones muffed a punt in the team’s win over the Patriots in Week 9, and Baltimore signed De’Anthony Thomas shortly thereafter. Thomas operated as the kickoff and punt returner on Sunday and will presumably remain in that role moving forward.

The team also waived DE Ufomba Kamalu, per Zrebiec.
