Westbrook’s Trevor Bates, a rookie linebacker from the University of Maine, was signed to the Indianapolis Colts practice squad Sunday, a day after he was cut from the team’s 53-man roster.

Bates played in all four preseason games for the Colts, making six tackles. A seventh-round pick in this year’s draft, he was moved to outside linebacker by the Colts after playing defensive end for Maine.

COWBOYS: Dallas officially signed Mark Sanchez as a backup quarterback but is keeping its options open with the injured Tony Romo.

Dallas added Sanchez to the 53-man roster on a one-year contract while waiving Jameill Showers, with the likely intention of adding the second-year player to the practice squad if another team doesn’t claim him.

Rookie Dak Prescott is set to start the opener Sept. 11 against the New York Giants, but the key to the quarterback puzzle remains Romo, who broke a bone in his back in a preseason game against Seattle.

The Cowboys can put Romo on the injured reserve-return list, which would free up a roster while sidelining the 36-year-old for the first seven games. They haven’t said how long he will be out following his fourth back injury in less than four years.

TEXANS: J.J. Watt passed his physical and will return to practice Monday, a good sign that he’ll be ready for Houston’s opener Sunday against Chicago.

Watt missed all of training camp after surgery to repair a herniated disc in his back in July.

RAVENS: Baltimore signed former Navy quarterback Keenan Reynolds to its practice squad.
