Marcellus Wiley: I'm nervous about the Cowboys in Week 8 with the severity of Dak Prescott's injury I SPEAK FOR YOURSELF

The Dallas Cowboys are red hot with their five-game winning streak, but there are questions about their star Dak Prescott. Dak was limited in Wednesday's practice with his calf strain as his Cowboys prepare to face another hot team in their Week 8 matchup: the Minnesota Vikings, who have won three of their last four games. Mike McCarthy gave an update on Dak, saying quote: 'He's going to practice, he's going through the individual part of it. He's in the game plan, so he's preparing to play..he's going to cross a threshold to make sure he's full go.' Marcellus Wiley explains why he's nervous about the Cowboys this weekend with Dak's injury.
