Nick Bosa Rehab Update: 49ers DE Still Sidelined
Aug 19, 2026
Bosa still sidelined with knee soreness
Nick Bosa hasn't practiced since Aug. 3, slowed by soreness and tendinitis in his surgically repaired right knee. Kyle Shanahan said Tuesday that the 49ers pass rusher is "making a lot of progress" in rehab — but he pointedly declined to attach any timeline to a return.
That's the whole picture as of now: encouraging words, no date. Progress is good; the absence of a target is the part worth flagging.
What it means for your survivor pick
Bosa is San Francisco's defensive engine, so an open-ended knee situation is a real variable if you're eyeing the 49ers in the coming weeks. Optimistic rehab talk doesn't equal a healthy Week 1, and "no timeline" from a head coach usually means the team itself isn't sure. For survivor purposes, that's a reason to keep San Francisco on watch rather than lock it in — the value of a defense built around Bosa drops if he's not on the field.
Don't burn the 49ers as a future-week option, but hold off committing until his practice status firms up. When the pick is this close to a coin flip, save your safest teams and revisit San Francisco once there's clarity. New to this?
