The Ravens signed defensive tackle C.J. Okoye to the 53-man roster Saturday before facing the Los Angeles Rams.
Baltimore waived undrafted rookie Reuben Lowery III after trading for veteran safety Alohi Gilman this week. Gilman is expected to make an instant impact.
One of the Ravens' three undrafted rookies to make the original 53-man roster, Lowery filled in for the injured Kyle Hamilton last week against the Houston Texans and was one of several young players pressed into action who had a tough game.
The 6-foot-6, 370-pound Okoye has played the past two weeks and made seven tackles and one quarterback hit. An international player from Nigeria, it's Okoye's first time on the 53-man roster. He spent his first two years on the Los Angeles Chargers' practice squad and started this season on Baltimore's practice squad.
The Ravens also activated quarterback Tyler Huntley and undrafted rookie safety Keondre Jackson from the practice squad.
Huntley will be Cooper Rush's backup with Lamar Jackson (hamstring) set to miss a second straight game. It will be Jackson's first NFL game. The 6-foot-2, 215-pounder from Illinois State will likely be used on special teams and will join Hamilton, Gilman, Malaki Starks, and Sanoussi Kane at safety.
