The San Francisco 49ers have re-signed running back Jeff Wilson Jr. on a one-year deal to strengthen their depleted backfield due to injuries. Wilson, a former 49ers player, returns amid concerns about the team's running back depth. The team also signed wide receiver Malik Turner, who has previous experience with the 49ers in 2022 and 2024, to bolster their wide receiver corps. Marques Sigle is emerging as a potential replacement for Jimmie Ward in the defensive backfield. Head coach Kyle Shanahan's offense features quarterback Brock Purdy, who has earned strong support from veteran leaders such as Trent Williams and is praised for his resilience and leadership. Purdy expressed enthusiasm about working with new offensive coordinator Mick Lombardi and highlighted the importance of Christian McCaffrey, who is projected by Pro Football Focus to rush for 1,096 yards in the 2025 season. Defensive coordinator Robert Saleh has returned to the team, receiving positive feedback from both veteran and younger players. Despite challenges in defense and receiver separation in 2024, Purdy managed a top-10 quarterback rating, underscoring his value to the team as they prepare for the upcoming NFL season.
