Broncos sign quarterback Austin Davis to back up Trevor Siemian, Paxton Lynch

ENGLEWOOD, Colo. — After deciding to cut veteran quarterback Mark Sanchez, the Broncos have signed five-year veteran Austin Davis, the team announced Saturday.

Davis signed a one-year deal and will be the third-string quarterback. He will serve as a “mentor” to starting quarterback Trevor Siemian and rookie Paxton Lynch, ESPN reports.

“He’s coming in to learn the offense. We’ll take it one step at a time,” Broncos general manager John 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.”

Davis has played with the Rams, Dolphins and Browns throughout his NFL career.

Davis went undrafted in 2012, but signed a free agent deal with the Rams before being cut in August 2013.

The Dolphins up picked Davis for their practice squad before he re-signed with the Rams in October 2013. He started eight games for the Rams in 2014. He threw 12 touchdowns and nine interceptions during his time with the Rams.

In 2015, Davis signed with the Cleveland Browns, where he competed with Johnny Manziel and Josh McCown for the starting job.

Davis was released by the Browns on Aug. 29.
