What happened: The 49ers' official account posted a question to fans on social media, asking which jersey was the first 49ers gear they ever owned. The prompt is inviting replies and photos from the team's fan base during the offseason.

Why it matters: The engagement post lands during a quiet stretch of San Francisco's calendar, with the roster still taking shape ahead of training camp. Recent offseason activity has centered on trade speculation involving Mac Jones and Brandon Aiyuk, plus the signing of backup left tackle Vederian Lowe.

What to watch: Fan replies will likely accumulate under the post as San Francisco continues offseason roster work before training camp opens.
