49ers DT Collins out for season with knee injury

San Francisco 49ers defensive tackle Alfred Collins will miss the entire 2026 NFL season after suffering a torn patellar tendon during practice in Melbourne, Australia. Coach Kyle Shanahan confirmed the season-ending injury on Wednesday, stating it occurred during Tuesday's practice session at AAMI Park. The loss comes just days before the 49ers are scheduled to play their season opener against the Los Angeles Rams at the Melbourne Cricket Ground. Shanahan expressed his disappointment, calling the injury a "big loss" and "real unfortunate for him." He noted that the team has now lost two defensive linemen for the year after final roster cuts and before the first game, presenting a significant challenge. Collins, a second-round pick in the 2025 NFL Draft, was expected to be a key contributor, likely serving as the probable starting nose tackle. In his rookie season in 2025, Collins appeared in 16 games, recording 16 tackles and forcing two fumbles, including a crucial play against the Rams last season that prevented a go-ahead touchdown. The 49ers' defensive line depth is further tested by other injuries.
