Williams was waived by the 49ers after reaching an injury settlement with the team on Thursday, Adam Caplan of ESPN.com reports.
Williams was placed on the Reserve/Non-Football injury list during the preseason and hasn't played a snap this season. He'll now look to find his way onto a another roster in need of defensive line help.
Williams was placed on the Reserve/Non-Football Injury list Saturday, Adam Schefter of ESPN reports.
This move was made to make room on the roster for offensive lineman Anthony Davis who was reinstated by the league from retirement Saturday. It remains to be seen when Williams will play again.
Williams' contract with the 49ers has been reworked into a one-year deal worth up to $6 million due to the uncertainty surrounding his availability for the beginning of the upcoming season, CSN Bay Area reports.
Williams initially agreed to a reported five-year, $27.5 million contract with the 49ers following a career year last season, but after he couldn't pass a team physical due to offseason ankle surgery, his contract was reworked into a one-year deal. A player that's had numerous procedures to his left leg during his pro career, Williams' status for the start of the 2016 season is in question following his latest operation, leaving the 49ers in need of some depth up front in case he's unavailable.
Williams inked a five-year contract with the 49ers on Wednesday, Cam Inman of the San Jose Mercury News reports.
On the heels of the 26-year-old's best campaign of his career, the club was able to secure the services of the 305-pound defensive lineman just before the start of free agency. He finished 2015 having played all 16 games, recording 65 tackles (45 solo), a sack, a forced fumble and a fumble recovery, a great output for a player who struggled with injuries early in his career. The totals exceeded his other three seasons combined, and put him in contention for an IDP slot in some leagues. He should fill a similar role with the 49ers in 2016, likely placing himself on the IDP radar once again.
