What happened: The 49ers plan to work out the same Jack Plummer who lined up Dolphins workouts next week, per Aaron Wilson of KPRC 2 Houston. Plummer went undrafted in 2024 and was waived by the Carolina Panthers last August before landing in the UFL.

Why it matters: San Francisco already carries four quarterbacks on its roster in Brock Purdy, Mac Jones, Kurtis Rourke and Adrian Martinez, so an outside workout signals Kyle Shanahan wants camp-arm depth rather than an open competition. Purdy has typically gotten rest reps during camp under Shanahan, and the staff has brought in extra arms for late-preseason snaps in past years.

What to watch: The workout is set for next week; whether it leads to a camp deal will depend on how Plummer throws.
