Broncos RB Javonte Williams tore his right ACL in Sunday's loss to the Raiders. That obviously ends his season. Melvin Gordon becomes the obvious name as top candidate to take over the Denver backfield, but Mike Boone has seen significant use each of the past 2 games. He stepped in to run nearly as many routes as Williams and Gordon in Week 3, and then Boone played more than Gordon against the Raiders. Gordon entered Sunday with a neck issue that limited him for a couple of practices, but he finished with a full workout. He did take a 2nd-half trip to the medical tent but returned. We'll see just how the new backfield split plays out. Boone is at least worth a pickup in most fantasy football leagues.
Update: In addition to the torn ACL, Williams also has a torn LCL and posterior lateral corner, sources tell NFL Network's Ian Rapoport. That figures to lengthen Williams' rehab timeline. We'll track his progress.
