Are the 49ers facing a roster crisis with a slew of sidelined stars?

ANSWER — As of April 9, 2026 (NFL offseason), the San Francisco 49ers have multiple players recovering from 2025 season injuries, listed as questionable for training camp or Week 1. Key injuries: George Kittle (TE, Achilles, hopeful for Week 1), Nick Bosa (DE, knee, expected training camp), Mykel Williams (DE, knee, expected training camp), Brandon Aiyuk (WR, knee, out—team expected to move on), Ji'Ayir Brown (S, hamstring), Nate Hobbs (CB, knee), Osa Odighizuwa (DT, elbow), Jake Tonges (TE, foot), Fred Warner (LB), and others including Kurtis Rourke (QB, knee), Tre'Vius Hodges-Tomlinson (CB), and more.[1]

EVIDENCE — ESPN injury page (updated through Mar 29, 2026) lists 15+ players questionable/out, with GM John Lynch updates: Kittle "hopeful" for Week 1 (NFL.com, Mar 29, 2026); Bosa/Williams ready for training camp (SFStandard.com via ESPN, Mar 29).[2][3] CBS Sports (Apr 1, 2026) echoes training camp questionables like Rourke (knee).[4] Official 49ers site shows playoff-era reports (Jan 2026), no new April update.[5] Conflicting: Covers.com says "no injuries to report."[6]

CREDIBILITY — 9/10 (Strong consensus from ESPN, NFL.com, team-linked reports; minor conflicts on "current" active list in offseason).
