ORCHARD PARK, N.Y. — Patriots defensive tackle Milton Williams will be active Sunday despite missing practice this week with a knee injury.

Williams is available after he was a non-participant in Thursday’s session and limited Friday. He’s been one of the Patriots’ best defensive players after signing a four-year, $104 million contract in free agency this offseason.

Patriots undrafted rookie wide receiver Efton Chism remained on the inactive list Sunday.

Chism, a training camp and preseason standout, has yet to make his NFL debut. Chism is currently buried on the depth chart behind Stefon Diggs, Kayshon Boutte, Mack Hollins, DeMario Douglas and Kyle Williams.

Rookie left guard Jared Wilson is expected to start at left guard next to left tackle Will Campbell, center Garrett Bradbury, right guard Mike Onwenu and right tackle Morgan Moses. Ben Brown, Vederian Lowe and Marcus Bryant will serve as depth.
