49ers' Kyle Shanahan provides crucial update on Nick Bosa's injury after Seahawks loss

Wagoner added an even more concerning report for 49er fans in a postgame conversation with Bosa.

“Asked his concern level that he might need to miss time, Bosa said ‘It's definitely there,'” Wagoner shared on his X (formerly known as Twitter) account.

One more 49ers insider in San Francisco Standard reporter David Lombardi noticed the effect Bosa's injury had on the Niners.

“Seattle didn't score a TD until Bosa was off the field. His injury essentially made a more competent offensive performance mandatory for the 49ers. They didn't deliver it,” Lombardi posted on X.

The 49ers' season appears to have fallen off the tracks. The defending NFC champions are losing ground in the race for the conference's top seed. And with an even record, the Niners are still a game behind the current NFC West leader the Arizona Cardinals.

Bosa is dealing with both a new injury, plus new struggles inside the 49ers' facility. However, he hasn't wavered from his confidence.

“We have a lot of games left. All we gotta do is get in the dance. I definitely still have confidence,” he said via KNBR postgame.

Bosa's status for next Sunday is now too be determined. San Francisco has a crucial November road battle against the 7-3 Green Bay Packers, who won off a blocked field goal in the closing seconds against the Chicago Bears.
