Trevor Siemian, the Broncos’ starting quarterback through their first four games, suffered a sprained AC joint to his left non-throwing shoulder last Sunday late in the first half of the Broncos’ 27-7 win at Tampa Bay. 

Lynch, a first-round pick out of Memphis, entered the game with a 14-7 lead and completed 14 of 24 for 170 yards, including a 5-yard touchdown to Emmanuel Sanders.
