As the NFL free agency period winds down, the San Francisco 49ers have focused on retaining their core players rather than pursuing new signings. With their top wide receiver, Brandon Aiyuk, sidelined for at least a month, the team faces a pressing need to identify a temporary replacement. Among the available free agents, veterans such as Amari Cooper and Keenan Allen are prime candidates to fill this gap, providing the 49ers with much-needed offensive support as they prepare for the upcoming season.
