The Broncos made some roster moves Tuesday afternoon.
They put running back Peyton Hillis on injured reserve. He suffered a torn hamstring in Sunday's win over Kansas City. Hillis is the fifth Denver tailback and 14th Bronco overall to be sent to the IR this season. As expected, the team promoted running back Cory Boyd from the practice squad to take Hillis' place.
Boyd, a rookie from South Carolina, is expected to be in the tailback mix down the stretch along with Tatum Bell, Selvin Young (who could play Sunday at Carolina for the first time since suffering a groin injury in early October) and P.J. Pope.
Also, Denver signed guard Pat Murray from Seattle's practice squad and cut safety Calvin Lowry. Lowry started three games this season after being claimed off waivers from Tennessee. He became expendable with Josh Barrett's strong play.
