Here are the key injury updates heading into the late games of Week Four:

• Cowboys RB Marion Barber (quad) is active and will start at Denver. He's a risky play because Tashard Choice will reportedly see the bulk of the workload, but he's available if you need him. As expected, RB Felix Jones (knee) is out.
• As expected, 49ers RB Frank Gore (ankle) is out. Glen Coffee will start vs. the Rams and is a terrific fantasy play.
