Hills carried the ball on the second and third plays of the game -- his first touch resulted in a first down. Hillis had six total yards on the Browns' game-opening touchdown drive.
Hillis originally was ruled out because of a severely strained left hamstring that forced him to miss six games, but his status was upgraded to a game-time decision when he was able to practice.
Both Hillis and Hardesty were listed as questionable Friday.
