Williams (leg) was released by the Chiefs on Wednesday, Terez A. Paylor of The Kansas City Star reports.
Williams was signed by Kansas City back in April and was always considered a long shot to make the team. He hasn't played in a regular season game since 2014 and will be hard pressed to make another roster for the start of the regular season.
Williams continues to battle a strained hamstring but may take part in mandatory minicamp on Tuesday, Terez Paylor of the Kansas City Star reports.
Williams has been out of the league for over a year after a promising 2012 campaign with the Buccaneers in which he caught 63 passes. While his hamstring injury doesn't appear to be critical, it's something to keep an eye on as training camp gets underway.
The Chiefs have signed Williams to a one-year deal, NFL Network's Ian Rapoport reports.
Williams, who didn't play in the NFL last season, last made a fantasy splash in 2012, when he caught 63 passes for the Bucs. He'll now look to secure a roster spot with the Chiefs, who continue to piece together needed wideout depth behind top option Jeremy Maclin. However, if Williams lands a spot on the 53-man roster, he'll be subject to a three-game suspension.
