Black Joins Niners' RB Race, McCaffrey's Backup Up for Grabs

San Francisco Forty-Niners add running back Black, aiming for backup reps behind Christian McCaffrey. Black competes with recent draftees Jordan James and Isaac Guerendo for key touches. Coach Kyle Shanahan praises Black as the second-best back in the 2026 draft class. The team seeks to strengthen their running back depth, as James and Guerendo have yet to deliver significant production. Training camp battles will determine who steps up, providing the Forty-Niners with valuable options in case of injuries to their lead runner.
