The Denver Broncos won't reveal who their starting quarterback will be for Sunday's game against the Atlanta Falcons until game day.

Trevor Siemian left Denver's Week 4 game with an injured shoulder, so Paxton Lynch took over under center.

"I'd take it all the way to game day," Gary Kubiak said. "I trust Trevor. He knows exactly what we're doing and he's very bright. He's on top of everything today. He's a part of the walk-throughs and everything that we're doing so he's on top of everything. We'll just see where he's at physically."

Even if he doesn't practice, Siemian believes he'll play.

"I think so," Siemian said. "I think you have to be able to. You don't get enough reps during the week as it is for every look. You have to make the most of what you see on tape and what you see in practice and go from there."
