Dak Prescott and the Cowboys are receiving good news about the quarterback's shoulder. An MRI on Saturday revealed Prescott's right shoulder strain is healing and he remains on track to play Week One against the Buccaneers. There also remains a possibility that Prescott plays this Saturday against the Texans in preseason to give the quarterback a series or two of game action. Garrett Gilbert, Cooper Rush and Ben DiNucci all have taken QB snaps for Dallas this preseason.
