The Ravens bolstered the middle of their offensive line Monday evening, signing center Hroniss Grasu to their 53-man roster.
A third-round pick in 2015, Grasu has started 12 games over the past three seasons (eight as a rookie and four last year). He missed his sophomore season because of a torn ACL.
The 6-foot-3, 301-pound Oregon product has good size and experience. He will step in behind Ravens starter Matt Skura, who has done a solid job so far. Baltimore also has rookie sixth-round pick Bradley Bozeman as another reserve interior lineman.
Grasu was released at the end of training camp as the Bears went with Cody Whitehair, a 2016 second-round pick, and rookie James Daniels, also a second-round pick, as their two center.
The Ravens waived defensive back Robertson Daniel to make room for Grasu on the roster.
