Broncos running back Ronnie Hillman had seven carries for 13 yards and a touchdown, adding one catch for three yards on one target, in Sunday's 24-12 win over the Lions.
Hillman scored a one-yard touchdown while C.J. Anderson was being evaluated for a concussion, but Anderson returned to play most of the snaps in the second half.
Neither running back had any luck on the ground, so while the Broncos may be growing restless with Anderson, they won't necessarily make a change. Despite missing a good chunk of the second quarter, Anderson outsnapped Hillman 35-24, according to Pro Football Focus.
