49ers Add Robbie Chosen in Major Roster Moves

The San Francisco 49ers have signed wide receivers Andy Isabella, Marquez Callaway, and Robbie Chosen, along with running back Ameer Abdullah and quarterback Carter Bradley, ahead of the 2025 NFL season. Isabella, who last played for the Steelers' practice squad and in the UFL, joins a unit missing key players Brandon Aiyuk and Jauan Jennings due to injury. Callaway brings experience from his time with the Saints and Buccaneers, while Chosen returns to the 49ers after playing for the Dolphins. The team released wide receivers Equanimeous St. Brown and Malik Knowles to make roster space. Offensive lineman Ben Bartch was activated from the non-football injury list. These transactions aim to bolster depth and competition as the 49ers prepare for training camp.
