According to Klis, Hillman sustained the injury early in the game while attempting to catch a pass, but returned to the game after he had his ankle taped.
In seven games this season, Hillman has run 91 times for 378 yards and three touchdowns. In Sunday's game, Broncos running back C.J. Anderson ran for 90 yards and turned a short pass from quarterback Peyton Manning into a 51-yard touchdown.
Running back Montee Ball started the first four games of the season for the Broncos, but left the team's Week 5 victory over the Arizona Cardinals with a strained groin. At the time, it was reported that Ball could miss up to three weeks, but including Sunday's game, he has missed five.
The Broncos (7-2) play the St. Louis Rams (3-6) on Sunday.
