Ian Williams is reportedly no longer a member of the 49ers.
San Francisco released the defensive tackle off reserve/NFL with an injury settlement, according to ESPN's Adam Caplan.
The 49ers originally agreed to a five-year contract extension with Williams in the offseason. However, the contract was amended to a one-year deal after he underwent a team physical after undergoing surgery on his left leg.
It is not known how Williams sustained the non-football injury in the offseason.
Williams, 26, a five-year NFL veteran, originally signed with the 49ers as an undrafted rookie from Notre Dame in 2011.
He played his first 16-game season in 2015. He ranked third on the 49ers with 85 total tackles, according to the stats compiled by the coaching staff.

Williams took over as the 49ers’ starting nose tackle in 2013 after the free-agent departure of Isaac Sopoaga.
But he started just 10 games over the next two seasons due to two fractures of his lower leg.
