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.
one more setback away from bustville. some replacement for defo. kinlaw cold man kinlaw cold
bustville? are you talking about kinlaw or shanahan or lance or lynch? you could basically pick one.
You cannot call a player a bust after one start
DT is one of the most difficult positions to transition to at the NFL level. He deserves some time, and has played very well against the run when he has played.
Once he develops some more moves and works in his technique he will be an absolute force in the middle. Just wait and watch…
It kills me how quick everyone is to want and kick the 49ers when they’re down and just need to get healthy and then refigure some things out..
Shanahan and Lynch are easily the most overrated combo in the sport. Tell us again how smart they were trading away Buckner.
I mean they did go from 2nd worst team in football to the superbowl in just 2 seasons, so there is that. Ask teams like the packers, ravens, saints and colts if they would rather make the playoffs every year yet fall short of their super bowl expectations, or go the niners route and make it 1 year and suck the other 3
i miss DeFo man
B-U-S-T
Having trouble deciding who was a worse pick Kinlaw Or Aiyuk
They were both EXCELLENT PICKS, just wait til the halfway point of next season..I’d easily bet you’d be eating your words .
I’d love To be wrong! How many catches does Aiyuk have this season?
