Former Northwestern quarterback Trevor Siemian has helped lead the Denver Broncos to a 4-0 record through the first four weeks of the season.

Peyton Manning may be gone, and now Siemian is still nicked up with a left shoulder injury, so the time is now for first-round pick, Paxton Lynch.

So far this season, Siemian has completed over 67 percent of his passes for 824 yards, six touchdowns and three interceptions. His standout game came on the road against the Cincinnati Bengals Week 3 when Siemian threw for 312 yards and four touchdowns without turning the ball over.

The Broncos face the Atlanta Falcons tomorrow at 4:05 p.m. EST on FOX.
