The Chiefs have promoted defensive tackle Derek Lokey to the 53-man roster from their practice squad.
The Chiefs, who have been one of the busiest teams in the NFL in roster moves this season, promoted Lokey after he spent the entire regular season on the practice squad. He was signed to a three-year contract.
Lokey was signed as a rookie free agent this spring. He played collegiately at Texas.
