Broncos second-year quarterback Trevor Siemian wasted no time getting his first NFL pass attempt, completion and first down out of the way.

Siemian went to the air on the very first snap of the game, connecting with a trusty target for all Denver quarterbacks, Demaryius Thomas.

Siemian was 3-for-5 for 28 yards on his first drive and the Broncos earned three first downs. However, rookie running back Devontae Booker fumbled on his first NFL touch, negating a 46-yard drive that had the Broncos in field goal range and looking for the end zone.
