Trevor Siemian took a sack in the first quarter of the Denver Broncos game on “Thursday Night Football” against the Indianapolis Colts and was carted to the locker room in Indianapolis.

What’s described as an injured left-shoulder, Siemian was labeled questionable to return. That left shoulder is the same one that Siemian had surgically repaired back in January.

Brock Osweiler, the back-up quarterback on Thursday, entered the game for Denver.
