Hillman left Sunday's game against the Packers in the third quarter with a thigh injury and is questionable to return, Nicki Jhabvala of the Denver Post reports.
Hillman got the start and scored a pair of first-half touchdowns, but C.J. Anderson mixed in frequently and was also effective. Shortly after Hillman was removed, Anderson scampered for a 28-yard touchdown, marking his first run of 15 or more yards all season.
