Polk had 11 carries for 34 yards and two catches for 14 yards (two targets) in Sunday's 27-6 loss to the Patriots.
According to Pro Football Focus, the running-backs snaps were divided between Polk (22), Jonathan Grimes (23) and Akeem Hunt (seven), with Alfred Blue active but not having a role on offense. Polk's workload is at least trending in the right direction the past few weeks, but he's still splitting snaps in an unproductive backfield.
