The Broncos put quarterback Trevor Siemian on injured reserve after he suffered a left shoulder injury in the first quarter of Denver's 25-13 win over the Colts on Thursday night, coach Vance Joseph announced. The move will end Siemian's third season in the NFL and send the Broncos into the offseason without a clear starting quarterback for next season.
The injury happened when Siemian was sacked and driven to the ground by Colts linebacker BarkeviousMingo while trying to escape the pocket. He was carted off the locker room and replaced by Brock Osweiler.
"I knew something wasn't right, right away," Siemian told reporters after the game. "It wasn't fun."
Osweiler was stellar in relief duty. He came into the game with the Broncos trailing 7-0 but ran for an 18-yard score in the first half and threw for two more in the second half to lead Denver to its second straight victory after an eight-game losing streak.
In the short time he played, Siemian went 5–for–9 with 67 yards and one interception. This season, the former Northwestern quarterback threw for 2,285 yards, 12 touchdowns and 14 interceptions.
Siemian was picked by the Broncos in the seventh round of the 2015 draft. He won a Super Bowl ring as the third-string quarterback behind Peyton Manning and Osweiler in 2016 and won the starting job in training camp battles in both 2016 and 2017.
