Williams (hip) didn't practice Wednesday, Zac Stevens of TheDNVR.com reports.
Williams suffered a hip flexor injury in this past Sunday's 31-28 win over the Bears, so the running back's status will be worth monitoring closely in advance of this weekend's contest against the Jets. If Williams is sidelined or available in only a limited capacity Week 5, Samaje Perine and Jaleel McLaughlin would be in store for added reps out of the Denver backfield.
