Paxton Lynch will see his first NFL start on Sunday.
The Broncos' rookie first-round quarterback will start ahead of an injured Trevor Siemian against the Falcons, NFL Network Insider Ian Rapoport reported Saturday.
Dealing with an AC joint sprain in his left shoulder, Siemian was limited in practice Friday and was initially listed as questionable to play against the visiting Falcons. Broncos coach Gary Kubiak said on Friday that Siemian would take more snaps on Saturday to test out the injured shoulder, and would then evaluate the starting quarterback's availability for Sunday.
