49ers defensive tackle Javon Kinlaw will undergo season-ending knee surgery, per a club announcement. Kinlaw will be placed on the injured reserve list and likely replaced with another interior lineman.
Kinlaw, who has battled intermittent knee trouble for years, met with a specialist in Los Angeles last week. He was told that surgery was likely, and an additional check confirmed the bad news for the former first-round pick.
“There’s lot things went into it and what they found. Good news is they think they solved the problem,” said head coach Kyle Shanahan (Twitter link via Cam Inman of the San Jose Mercury News).
Kinlaw has yet to fill DeForest Buckner‘s shoes in SF. So far, the second-year pro has taken a backseat to Nick Bosa, Dee Ford, Arik Armstead and the rest of the Niners’ standout linemen. His season will end with just eight tackles in four games.
On the plus side, quarterback Trey Lance may be able to face the Bears this weekend. Left tackle Trent Williams is also expected to play as the 49ers look to snap their four-game losing streak.
