Broncos quarterback Trevor Siemian returns to practice

ENGLEWOOD, Colo. — Broncos quarterback Trevor Siemian practiced for the first time Thursday since injuring his left nonthrowing shoulder against the Tampa Bay Buccaneers.

Siemian did some throwing in the initial open period of practice at the Broncos’ training facility, though it was limited.

Siemian suffered a shoulder injury in Sunday’s 27-7 win over the Tampa Bay Buccaneers.┬áThe injury came late in the first half when Siemian was sacked and body-slammed to the turf by Buccaneers defensive tackle Clinton McDonald, landing hard on the shoulder.

He was replaced by first-round draft pick Paxton Lynch, who led the offense to two field goals and a touchdown.

Kubiak said Siemian didn’t need to practice to start Sunday’s game against the Atlanta Falcons at Sports Authority Field at Mile High (2:05 p.m. kickoff on FOX31), but he needed to show he is physically able to play.

Kubiak said Wednesday that Siemian was “feeling a lot better than he was coming out of the game.”

Siemian is listed as day to day and whether he or Lynch starts likely will be a game-time decision.
