San Francisco 49ers place Isaac Guerendo on PUP list

Summary

The San Francisco 49ers placed running back Isaac Guerendo on the physically unable to perform list on August 30. This designation requires the third-year player to miss at least the first four games of the 2026 season due to a torn pectoral muscle. Guerendo, who was drafted by the organization in the fourth round of the 2024 NFL Draft, spent much of his previous time on special teams. He recorded 84 carries for 420 yards and four touchdowns during his rookie year but did not receive any carries in 2025. With Guerendo unavailable, the backfield behind Christian McCaffrey will feature Kaelon Black and Jordan James as the team finalizes its 53-man roster. He remains sidelined while recovering from the injury sustained during the off-season.
