Nick Bosa is a defensive lineman, so this news has zero relevance in standard/PPR leagues but matters significantly in IDP (Individual Defensive Player) formats, where he's typically a top-5 DL target. Knee tendonitis is a chronic, often lingering issue rather than an acute injury — it can flare up during a season and limit explosiveness/pass-rush snaps even if he technically suits up. If Bosa is limited or inactive Week 1, it also modestly dings the 49ers' team DST in IDP/standard defense scoring, since he's their primary pass-rush and sack producer; a diminished pass rush could reduce sacks/pressures and give Matthew Stafford more time against a compromised front.
