Cowboys part ways with offensive coordinator Kellen Moore

FILE - In this Jan. 3, 2016, file photo, Washington Redskins outside linebacker Trent Murphy (93) applies pressure as Dallas Cowboys quarterback Kellen Moore (17) during the first half of an NFL football game in Arlington, Texas. Two years ago, Moore went into training camp as the backup to Tony Romo before breaking an ankle in practice. Because of that injury, Prescott became the starter when Romo injured his back in a preseason game. (AP Photo/Michael Ainsworth, File)
