Defensive coordinator Dean Pees said he wasn't sure of the severity of the injury, adding, "I think it was something in special teams. I don't know exactly what it was, but it was in the special teams practice that he did something. I really don't know exactly what it was."
Cornerback Lardarius Webb, who was excused from Friday's practice to attend to a personal matter, returned and participated in Saturday's session. Offensive tackle Ramon Harewood (rolled ankle) and center/guard Justin Boren (undisclosed) missed practice for the second consecutive day.
