On Saturday the Chiefs promoted rookie S Neiko Thorpe from the practice squad to the active roster.
With CB Jalil Brown, CB Brandon Flowers and FS Kendrick Lewis battling injuries the secondary could be depleted on Sunday against Baltimore if all three can’t play.
To make room for Thorpe, they released C/G Bryan Mattison, who was signed just over a week ago and had not played in a game with the Chiefs.
The 6-2, 185-pound Thorpe was not drafted coming out of Auburn, where he played 51 games and started 40 over his career. He was released on the final roster reduction before the start of the regular season and then was signed to the practice squad.
The 22-year old native of Tucker, Georgia has been wearing No. 38 in practice.
