Marquez Callaway signed with San Francisco, along with running back Ameer Abdullah, quarterback Carter Bradley and wide receiver Andy Isabella. The 49ers released wide receiver Equanimeous St. Brown and waived offensive lineman Sebastian Gutierrez, wide receiver Malik Knowles and safety Jaylen Mahoney.
