Dallas Cowboys quarterback Tony Romo has two fractured transverse process in his back, according to ESPN.

However, Romo hasn't been ruled out for Sunday's game against the Arizona Cardinals

This isn't related to his back surgery last year. He's expected to return this season. Baylor quarterback Bryce Petty had the same injury and missed only one game.

If Romo's out, Brandon Weeden would start and rookie Dustin Vaughan would be the backup.
