Dak: "No doubt" I'll be 100% for Week 1

Cowboys QB Dak Prescott (shoulder) told NFL Network's Tom Pelissero that he has "no doubt" he'll be 100% for Week 1. Pelissero adds that Prescott has had no setbacks in his rehab and could have played vs. Houston on Saturday night if it was a regular-season game. Dallas reportedly plans to ramp up Prescott's reps in practice this coming week and have him be a full-go during the week leading up to the Thursday night opener vs. the Bucs
