49ers defensive tackle Alfred Collins sustains season-ending knee injury
Summary

San Francisco 49ers defensive tackle Alfred Collins will miss the entire 2026 season due to a torn patellar tendon. The injury occurred during a practice session this week in Melbourne, Australia, where the team is preparing for their season opener against the Los Angeles Rams. Head coach Kyle Shanahan confirmed the diagnosis on Wednesday. Collins, a 2025 second-round draft pick, recorded 17 tackles and one sack during his rookie campaign. The 49ers depth at the position is currently affected by other injury concerns, as James Thompson Jr. and Gracen Halton have recently dealt with hamstring and ankle issues, respectively. The organization may look to practice squad players Sebastian Valdez or Kevin Givens to bolster the defensive line for the upcoming game.
