49ers DT Alfred Collins suffered a torn patellar tendon and is out for the 2026 season.

09 September 2026

Collins tore his patellar tendon during the 49ers’ first Australia practice last night. It’s an unfortunate break for the 2025 second-round pick, set to start Week 1 for the 49ers defensive line against the Rams. Collins’ biggest play last season was forcing a goal-line Kyren Williams fumble in Week 5. He will instead need knee surgery and begin a journey back from injury for 2027. The 49ers will reach into their defensive tackle depth and may activate Kevin Givens or Sebastian Valdez from the practice squad for Week 1 in Australia against the Rams.
