San Francisco 49ers defensive lineman Alfred Collins suffers season-ending knee injury

San Francisco 49ers defensive tackle Alfred Collins will miss the entire 2026 NFL season after tearing his patellar tendon during practice on Tuesday. Head coach Kyle Shanahan confirmed the injury occurred shortly before the team’s 11-on-11 drills in Australia, where the 49ers are currently preparing for their season opener against the Los Angeles Rams. The loss of Collins creates further depth concerns on the defensive interior, as the team is already managing a broken foot for defensive lineman Sam Okuayinonu. The organization plans to place Collins on injured reserve following his upcoming knee surgery. This setback marks the second defensive lineman sidelined for the year for San Francisco prior to the start of the regular season. The team remains in Australia while continuing preparations for their matchup against the Rams.
