According to Jennifer Lee Chan, 49ers CB K’Waun Williams sprained his knee in Sunday night’s loss to the Eagles and is a likely candidate to go on short-term injured reserve for a few weeks while he recovers.
Ian Rapoport adds Williams has a rare ACL sprain. He does not need surgery to repair the ligament and if his rehab goes well, Williams could miss just the three weeks he’s required to stay on IR, per Rapoport.
Williams, 29 wound up signing on with the Browns as an undrafted free agent out of Pittsburgh back in 2014. He was in the final year of his three-year, $1.53 million contract when the Browns cut him loose during the preseason as they trimmed their roster down to 75 players.
Williams was later claimed off of waivers by the Bears, but he failed a physical due to his ankle injury and was cut loose a day later. The 49ers signed him to a one-year, $765,000 contract in February, 2017, before later signing him to a three-year extension at the start of the regular season.
San Francisco picked up Williams’ option this past offseason.
In 2020, Williams has appeared in four games for the 49ers and recorded 12 tackles, no sacks or interceptions and two pass defenses for the 49ers.
