Source: Mark Sanchez will sign with Cowboys after Broncos cut him

— -- Mark Sanchez will sign with the Dallas Cowboys after being released by the Denver Broncos, a source tells ESPN.

Sanchez's future in Denver looked bleak after Broncos coach Gary Kubiak named Trevor Siemian his starting quarterback and had rookie Paxton Lynch take all the snaps in the team's preseason finale against the Arizona Cardinals.?

Earlier this week Sanchez, who was traded to Denver by the Philadelphia Eagles in March, said he was determined to handle things in a "professional way.''

Sanchez was 20-of-30 passing for 219 yards and one touchdown, with one interception, in two preseason appearances, including a start in the preseason opener in Chicago. He also lost two fumbles in the closing minutes of the first half of the preseason game against San Francisco, meaning he had three turnovers in 46 snaps on the field.
