Williams sat out Wednesday's practice with a listed quadricep injury.
Williams exited the Broncos' Week 4 win over the Bears in the first half with what was originally cited as a hip flexor, but the team is labeling his injury differently three days later. Regardless, Williams' status for Sunday's game against the Jets is unclear, but the Broncos will see what, if anything, he's able to do Thursday and Friday before ruling on his status. If Williams is sidelined this weekend, Samaje Perine and Jaleel McLaughlin would be in line to see expanded roles out of the backfield.
