​In another sign that Tony Romo is on his way out the door in Dallas, the Cowboys have re-signed a backup quarterback for Dak Prescott.

Yup, Kellen Moore will be back in the Big D next season. 

Moore entered the 2016 campaign as the team's No. 2 QB, but similar to Tony Romo, he also suffered an injury before the season. This opened the door for Dak Prescott. 

The rest is history.

Despite the signing of Moore and the presence of Prescott and Romo on the roster right now, the Cowboys may not be done tinkering with the quarterback position.

Moore, out of Boise State, made three appearances and two starts for the Cowboys in 2015, completing 61 passes for 779 yards, four touchdowns and six interceptions.

He hasn't appeared in an NFL game outside of the 2015 season and currently holds an odd distinction as the only active left-handed quarterback in the league.
