Key Points:

49ers defensive tackle Alfred Collins suffered a season-ending patellar tendon tear during practice, as confirmed by coach Kyle Shanahan.
Collins was a limited participant in Tuesday's practice, and his injury leaves the team with limited depth at the defensive tackle position.
The 49ers currently have Osa Odighizuwa, CJ West, Gracen Halton, and James Thompson Jr. available, though Thompson and Halton are dealing with injuries.
The team is expected to promote a defensive tackle from the practice squad, likely Sebastian Valdez or Kevin Givens, for their upcoming game.
Collins, a 2025 second-round pick, appeared in 16 games last season, recording 17 tackles, one sack, and several impactful plays.
