Even though the Denver Broncos were off Tuesday, it was an insanely busy day inside Dove Valley.

First the team broke ground on their new practice facility. Then they announced numerous roster changes.

Safety Rahim Moore was placed on injured reserve with a designation to return due to having emergency leg surgery. That means he can begin practicing in six weeks (Dec. 31) and can play in eight weeks (Jan. 14).

With Moore on the IR, the team signed Michael Huff to add some depth to the active roster.

Huff is an eighth-year player who has seen action in 115 regular-season games (94 starts) with Oakland (2006-12) and Baltimore (2013). He has 461 tackles, 5.5 sakcs, 11 interceptions, 54 passes defensed, four forced fumbles, and two fumble recoveries to his name. He was a first round draft pick (7th overall) by the Raiders in 2006.

The Broncos also signed safety John Boyett to the practice squad and released running back Edwin Baker. Boyett is a rookie who was taken by the Colts in the 6th round of the 2013 draft out of the University of Oregon. He was waived by the Colts on Sept. 3.
