The Broncos added a third quarterback to their roster Saturday with the addition of veteran quarterback Austin Davis.

Davis signed a one-year deal and will join starting quarterback Trevor Siemian and rookie Paxton Lynch in the quarterbacks room.

Executive Vice President of Football Operations and General Manager John Elway foreshadowed the move on Saturday when he spoke to the press.

"It'll be a veteran," Elway said. "We're working on it."

The five-year veteran started eight games for the St. Louis Rams in 2014 and threw for 12 touchdowns, nine interceptions and more than 2,000 yards. During that stint, he averaged just over seven yards per completion and compiled a quarterback rating of 85.1.

Davis spent the 2015 season and part of the 2016 preseason with the Cleveland Browns. He'll be on the sidelines Thursday night against Carolina.

"He's coming in to learn the offense, we'll take it one step at a time," Elway said. "Let's put it that way. Any time you bring in a guy this late, it's gonna take some time to get him turned around. Trevor's the guy. We've got a lot of confidence in Trevor and believe that he can do the job. It's Trevor's job, and he's not going to be looking over his shoulder."
