In the aftermath of center Matt Skura's season-ending knee injury, the Ravens signed a former player to add depth to their offensive line.
The Ravens claimed center Hroniss Grasu off waivers Wednesday, one day after he was released by the Tennessee Titans. To make room for Grasu on the 53-man roster, the Ravens waived defensive lineman Zach Sieler.
Grasu played three games with the Ravens last season before being released. He was a third-round draft pick of the Chicago Bears in 2015, where he played for three seasons, and Grasu has also been with the Miami Dolphins (2018).
Grasu's likely role will be to backup center Patrick Mekari, who took over as the starter after Skura went down Week 12 against the Los Angeles Rams. Mekari, an undrafted rookie from Cal, played well against the Rams and during Sunday's 20-17 victory over the San Francisco 49ers.
However, the Ravens released center Jake Brendel on Nov. 30 after he was signed just three days earlier. Grasu has played 17 games during his career with 13 starts, giving the Ravens a more experienced backup if needed.
Sieler's release comes after he played in just four games this season with two tackles. He has not been active since Week 10 and the Ravens have added three veterans this season who have all been regulars in the defensive line rotation – Jihad Ward, Domata Peko Sr. and Justin Ellis.
