What happened: Aiyuk's latest social-media barrage targeted Kyle Shanahan, extending his public dispute with San Francisco. Armando Salguero said NFL personnel people noticed the activity and reacted negatively.

Why it matters: That perception could narrow Brandon Aiyuk's options as teams assemble their 2026 rosters. It also deepens a relationship rupture that has dominated his offseason.

What to watch: Watch for formal action on Aiyuk's 49ers status and signs of interest as training camps progress.
