"Trevor is our starting quarterback," coach Gary Kubiak said Monday, via The Denver Post. "Hopefully he's going to be OK. ... We feel fortunate with Trevor. We'll be day-to-day here"
Kubiak added that Siemian has a non-throwing sprained shoulder: "He's just really, really sore going through that throwing motion."
Siemian got crushed early in the Broncos win over the Tampa Bay Buccaneers on Sunday, leaving before halftime after getting tossed to the ground by defensive tackle Clinton McDonald -- the third sack he took on the day. Siemian stood on the sideline the entire second half and would have returned in an emergency situation.
Lynch's solid play could have allowed Kubiak to turn to his big-armed, first-round draft pick.
The coach is comfortable going back to Siemian. The second-year signal-caller showed he could push the ball vertical in Weeks 3 and 4 after coaches employed a more conservative game plan the first two games of the season.
"Obviously they're both good players. ... Probably going to need them both. It's just the nature of the business these days," Kubiak said of his quarterbacks.
We didn't expect Lynch to sit on the bench the entire season. For now, however, Kubiak is comfortable letting his rookie learn mostly from the sidelines unless injury forces his hand or Siemian's play slips southward unexpectedly.
