The Chiefs waived linebacker Dezman Moses on Saturday and signed linebacker Devan Walker to take his place on the 90-man roster.
Walker, 24, is listed at 6 feet 3 and 240 pounds. He went undrafted out of Southeastern Louisiana in 2013 and was waived-injured by the San Diego Chargers last August after suffering a knee injury.
Moses, who is listed at 6 feet 2 and 249 pounds, injured his elbow on Saturday and had surgery on Thursday. A third-year pro, Moses had five tackles in 13 games last season. As a rookie with Green Bay in 2012, he had 27 tackles and four sacks in 16 games.
