Williams was listed as a limited practice participant Wednesday due to a knee injury, George Stoia III of The Denver Gazette reports.
In addition to Williams, fellow running back Melvin Gordon (thumb/hip) was listed as a limited participant to begin Week 15 prep, which was fully expected after he emerged from Sunday's win over Detroit with a sprained thumb. In the case of Williams, his appearance on the injury report is more of a surprise, as the Broncos didn't disclose that he hurt his knee at any point during Week 14. His practice activity will bear monitoring over the next two days to gain a sense of his chances of playing this weekend against the Bengals.
