The Denver Broncos grabbed their fifth with of the season on Thursday night after topping the Indianapolis Colts 25-13. This victory had very little to do with starting quarterback Trevor Siemian, as he was forced out of the game early.

It has now gotten even worse for the gunslinger, as Trevor Siemian has seen his 2017 campaign come to an abrupt end due to a shoulder injury that put him on the season-ending injured reserve on Friday, according to Nicki Jhabvala of the Denver Post.

An MRI taken in Colorado on Friday confirmed that Siemian suffered subluxation, or a partial dislocation, of his left (non-throwing) shoulder — the same one he had surgically repaired — and will be placed on season-ending injured reserve. Broncos coach Vance Joseph said Siemian will not require surgery; just rest and rehabilitation.

Siemian suffered the injury late in the first quarter after being tackled by Colts linebacker Barkevious Mingo while attempting to scramble toward the sideline. He had landed in an awkward position that forced his left arm to be jammed in his shoulder causing him to favor his left arm when being looked at by the team's medical staff. Shortly thereafter, he was carted to the locker room for further examination.

The loss of Siemian now puts another bind on the Broncos' quarterback situation with the likely starter being Brock Osweiler. He had come on in relief on Thursday night, helping lead Denver to a comeback win by completing 12-of-17 passes for 194 yards and a pair of touchdown along with rushing for another touchdown.

Head coach Vance Joseph stated on Friday that the team will address the situation fully next week with a starter in place.

Second-year quarterback Paxton Lynch will factor into the equation, as he's expected to be cleared practice by Sunday after missing the last three weeks due to an ankle injury. Lynch has made one appearance this season in his lone start against the Oakland Raiders on Nov. 26, where he hurt his ankle.
