Hall was signed by the Chiefs again on Friday after recently being let go. He was claimed off waivers from San Francisco on Sept. 1 and played in eight games, catching one pass for nine yards, before he was released.
Powe, the Chiefs' sixth-round pick in the 2011 draft, was released to make room for Hall. Powe also was released before the start of this season, and then rejoined the team on Dec. 3. He's played in only 10 games and made six tackles in roughly two seasons in the league.
