San Francisco 49ers defensive tackle Alfred Collins is ruled out for the season after sustaining a knee injury in Melbourne. Multiple reports say he is injured during team activity in Australia and will not return for the remainder of the year.

The injury occurs ahead of the 49ers’ scheduled opener in Australia against the Los Angeles Rams, with outlets noting the timing as just days before the matchup. One report attributes the determination to coach Kyle Shanahan, who says Collins is out for the season. Other coverage frames the development as a significant setback for a young defensive lineman entering his second NFL season.

Across the sources, the focus stays on the same core facts: the knee injury happens in Melbourne, the team concludes it is season-ending, and the loss arrives immediately before the Rams game in Australia. The reports differ mainly in wording and emphasis, such as labeling Collins as promising or specifying the proximity to the opener, rather than disputing any details of the injury or timeline.
