San Francisco 49ers defensive tackle Alfred Collins has been ruled out for the remainder of the 2026 NFL season. The team confirmed that Collins suffered a torn patellar tendon during a practice session held in Australia this past Tuesday.

This injury represents a significant loss for the 49ers' defensive line, as Collins was slated to be a primary starter for the upcoming campaign. A torn patellar tendon is a severe injury that typically requires surgery and an extensive rehabilitation period, making a return to the field within the same calendar year medically improbable for professional athletes.

The 49ers are currently in Australia as part of the league's international outreach and preseason preparation efforts. While the team has not yet announced a specific replacement for Collins, the coaching staff will likely need to adjust their defensive rotation to compensate for the vacancy created by his absence. The organization has not provided further details regarding the specific circumstances of the practice drill during which the injury occurred.
