The team made official on Tuesday what Head Coach Mike Shanahan announced on Monday. Peyton Hillis was placed on the Reserve/Injured list today with a hamstring injury, and running back Cory Boyd was upgraded from the practice squad to the active roster.

The team also waived safety Calvin Lowry on Tuesday, signing guard Pat Murray off the Seattle Seahawks’ practice squad to fill the roster spot.

Boyd, signed by Denver to its practice squad on Nov. 4, is a rookie out of the University of South Carolina. He racked up 2,267 rushing yards and 1,303 receiving yards in 46-game career as a Gamecock. He is just the second player in school history to amass 2,000 rushing yards and reel in 100 receptions. He is also just the second player in school history to have 1,000 yards rushing and receiving.

Hillis, a rookie out of Arkansas, emerged as the Broncos’ go-to back after injuries plagued the backfield early in the season. He leads the team with 343 rushing yards and five rushing touchdowns. His six total touchdowns (5 rush., 1 rec.) are tied for the team lead with Brandon Marshall.

Murray was originally signed by Green Bay as an undrafted rookie free agent in 2007. He played in 41 games with 32 starts at Division II Truman State, earning first-team All-Mid-America honors in 2006.
