Trevor Siemian is not practicing Friday and is ruled out for the Denver Broncos’ game Sunday at Jacksonville, according to NFL player sources.
First-round rookie quarterback Paxton Lynch will start. Broncos head coach Gary Kubiak is expected to make the quarterback switch official following practice Friday.
As uninspiring as Siemian's play was at times, he has a solid 7.4 YPA and has thrown 1.5 TD per game. Lynch is a downgrade for both Demaryius Thomas and Emmanuel Sanders, though both receivers had solid outings -- 5-49-1 and 7-80, respectively -- when Lynch started against the Falcons.
