ENGLEWOOD, Colo. —The Broncos elevated linebacker Vontarrius Dora to the active roster Friday and placed long snapper Casey Kreiter on injured reserve in a corresponding move.

Dora, a 6-foot-4, 256-pound rookie, has spent the season on the Broncos practice squad. He joined Denver in May as a college free agent from Louisiana Tech. As a four-year starter in college he totaled 147 tackles, 13.5 sacks, two forced fumbles and two fumble recoveries.

He was named Honorable Mention All-Conference USA following his senior season.

Kreiter has not played since the Broncos' game against the New Orleans Saints on Nov. 13. The Broncos signed veteran Thomas Gafford as a replacement, and he has snapped in the three games since Kreiter's injury.
