Denver Broncos quarterback Trevor Siemian’s third year in the NFL did not go too well. Apart from regressing from his second-year numbers this season, Siemian also suffered a shoulder injury back in December that now requires surgery.

According to Jeff Legwold of ESPN, Siemian is set to go under the knife to repair an injured left shoulder he hurt during the Broncos' Week 15 road win against the Indianapolis Colts.

Siemian underwent an evaluation Tuesday in Los Angeles and will have surgery Wednesday to repair the damage from a dislocation suffered Dec. 14 against the Indianapolis Colts. Siemian was sacked by linebacker Barkevious Mingo and landed hard on his non-throwing shoulder.

This is the 26-year-old signal-caller’s second straight year to go on the operating table to fix the same body part, though Siemian said that the two surgeries addressed two different issues on his shoulder.

After passing for 3,401 yards to go with 18 touchdowns, and 10 interceptions in 14 games in 2016, Siemian took a step back this season, finishing the 2017 campaign with just 2,285 passing yards, 12 touchdown passes, and 14 interceptions, though in three fewer games.

Siemian’s timetable for recovery is 8-12 weeks, making him available for the OTAs. The Northwestern product’s rookie contract expires at the end of the 2018 season, so he is going to be pressed to play much better than he did this season. That said, it’s not even certain whether he will ever again get his starting role in Denver.
