FRISCO, Texas - One day after releasing him from the 53-man roster, the Cowboys have added quarterback Jameill Showers to the practice squad.

For the second straight season, it appears Showers will begin the season the developmental squad, a place he spent all of last year.

Showers had a shot to become the backup quarterback this season behind rookie Dak Prescott, and was on the Cowboys' initial 53-man roster after Saturday's cut deadline. But the team decided to sign veteran Mark Sanchez, who was officially added to the roster on Sunday, as the Cowboys released a Showers to make room.

After clearing waivers, Showers returned to the team, where he will likely run the scout-team offense in practice, along with Sanchez.

[embeddedad0]A year ago, Showers had many roles in practice, serving as a quarterback mostly but also played safety, receiver and ran scout-team special teams. This year, Showers could still end up with similar duties, but it's been clear the Cowboys are more committed to seeing him develop as a passer. Showers played in all four preseason contests, including the entire game last week vs. Houston.

"Jameill has really improved as a quarterback in his time here," head coach Jason Garrett said. "A real tribute to him and how hard he's worked at it. The biggest thing for a young quarterback is to play. You have to play in games, and that's where you learn the most. He did a lot of good things over the course of the preseason with the snaps he got in games. Then, there's certainly a lot of things he can learn from. But he's a good football player. He's a good person. It's good to have him on your team for a lot of different reasons. He's just young, and he's developing as a player. So that position is so important and having a veteran guy, a veteran presence like Sanchez I think will help our team going forward."
