What happened: Kyle Shanahan said the injury occurred during practice this week. The second-year defensive tackle had been listed as a limited participant Tuesday.

Why it matters: Osa Odighizuwa remains available, while James Thompson Jr. missed practice with a hamstring injury and Gracen Halton was limited by an ankle injury. Those issues leave San Francisco managing multiple concerns along its interior line before the opener.

What to watch: San Francisco could elevate Sebastian Valdez or Kevin Givens from the practice squad before Thursday's game.
