Winners of two straight outings, Denver enters the game at Soldier Field at 5-5, and tied for the lead in the AFC West, but once again relying on a relatively inexperienced tailback to carry the load.
The Broncos have a history of unearthing tailbacks in the late rounds of the draft or as free agents, and hope that Hall can be the next in a long series of success stories.
Hall, 25, carried seven times for 89 yards and one touchdown in last Monday night's victory over the Tennessee Titans. His big play was a 62-yard touchdown run on which he burst off tackle and outraced the Tennessee secondary.
In five appearances this season, Hall has carried just 15 times for 108 yards. But the former South Florida standout, signed by Denver to its practice squad last November, is the kind of one-cut runner who often flourishes in the Broncos' zone-blocking system.
The No. 2 tailback for Sunday's game will be Mike Bell, who has spent much of this season playing fullback.
Henry continues to be plagued by a sprained knee ligament that has now sidelined him for three games. The seven-year veteran, who leads the Broncos with 580 yards on 128 carries, is also awaiting word from the NFL on his appeal of a pending one-year suspension for a repeat violation of the league's substance abuse policy.
The rookie Young, signed as an undrafted free agent after a solid career at the University of Texas, has rushed for 385 yards on 76 attempts, but suffered a knee sprain on Monday night.
