Williams suffered an injury to his right knee in the win over Oklahoma State, and is currently listed as questionable.
If Williams can't go, safety Earl Thomas could replace him in the lineup. After Williams was injured this past Saturday, Thomas slid over to corner to replace the sophomore.
The good news, though, is that Williams is the only real bad news on the injury front; the corner is the only player from the two-deep depth chart listed on the injury report.
