The Kansas City Chiefs announced the signing of free-agent wide receiver Mike Williams on Monday.

Official terms of the agreement were not disclosed, but Williams is joining the club on a one-year contract, a source told Ian Rapoport of NFL Network.

Williams adds some further depth and competition to the position coming off a 2015 season in which Kansas City's passing game took a significant step forward.

A former fourth-round pick of the Tampa Bay Buccaneers, Williams last played with the Buffalo Bills in 2014.

His most impressive season came as a rookie in 2010, when he hauled in 65 receptions for 964 yards and 11 touchdowns.
