The Bears announced a pair of roster moves on Tuesday morning.
They have signed defensive back Marlen Sewell. He takes the roster spot of defensive lineman Jonathan Garvin, who was placed on injured reserve in a corresponding move.
Sewell was undrafted out of Vanderbilt this year. He signed with the Chiefs after the draft, but was let go by Kansas City in June. He had 52 tackles, 1.5 tackles for loss, a half-sack and two passes defensed for the Commodores last season.
Garvin played in 38 games for the Packers between 2020 and 2022, but has not appeared in a game over the last three seasons.
