Mark Sanchez signs with Cowboys after being cut by Broncos

Mark Sanchez has found his landing spot after being released by the Denver Broncos on Saturday.

Sanchez signed a contract with the Dallas Cowboys, the team announced.

The Cowboys were in the market for a quarterback after Tony Romo suffered a broken bone in his back, leaving rookie Dak Prescott and Jameill Showers as the only options at quarterback. Sanchez is expected to be Prescott's backup while Romo is out.

Sanchez became expendable in Denver after the Broncos named Trevor Siemian the team's starting quarterback on Monday.

When Sanchez was traded to the defending Super Bowl champions in March, the veteran appeared to be the prohibitive favorite to become Peyton Manning's successor. But Siemian, the second-year pro who has not thrown a pass in the regular season, had more experience in Broncos coach Gary Kubiak's system, and his steady play in preseason helped him seal the starting job.

After releasing Sanchez, the Broncos signed Austin Davis as a backup to join Siemian and first-round pick Paxton Lynch on the roster.
