ENGLEWOOD, Colo. -- The Denver Broncos quietly reached a roster milestone for the 2014 season at the opening of Thursday's practice.

For the first time since the team opened training camp July 24, the Broncos had every player on the roster in uniform and participating in practice. Safety David Bruton Jr. (ankle) and guard Louis Vasquez (rib cage) were limited in Thursday’s work but did participate in most of the workout.

Because of injuries and excused absences, the Broncos had not had 100 percent participation for any full practice before Thursday. Wide receiver Demaryius Thomas had missed the opening days of training camp because of a death in his family, and by the time he returned the team had a smattering of players suffer injuries that required them to miss time.

Linebacker Danny Trevathan also returned to practice last week after he had suffered a fracture on the top of his tibia in an Aug. 12 practice. Trevathan has practiced fully all week and is set to return to the lineup in his weakside position.

Defensive coordinator Jack Del Rio said Thursday that given Trevathan didn’t play in the preseason or in the Broncos’ first three games of the regular season, the linebacker’s snap count would likely be monitored.

“I think we’ll anticipate -- I’m not sure exactly -- but at some point we will spell him during the game and not count on him going out there playing 80 plays or whatever right away," Del Rio said.

Asked if he was really hoping the Broncos would play a defense-sapping 80 plays, Del Rio added, “Well, 45 would be fine."
