The Chiefs promoted defensive back Daniel Sorenson to the 53-man roster Saturday, waiving defensive end Damion Square in a corresponding move.
Sorenson played in the team's regular-season opener but hasn't seen game action since. He was signed to the team's practice squad Sept. 11. Square came over to the team on waivers before the season but has been inactive each week.
The Chiefs also signed tackle Curtis Feigt to the practice squad Saturday.
