Chiefs signed TE Kevin Brock.

Brock has been bouncing around the league for the past four seasons, but he's appeared in just two career games, both with Buffalo in 2011. He has two catches for 27 yards. The 6-foot-5, 249-pound Rutgers product will be aiming for a special teams job.

Bills promoted TE Kevin Brock from their practice squad.

Brock will take injured rookie TE Lee Smith's place on the 53-man roster. A former Raider and Bear, Brock has never appeared in a regular season game.
