The Dallas Cowboys had initially assumed the bye week hit at a perfect time with star quarterback Dak Prescott dealing with a calf injury. Now, even after time to rest and and try to heal, it appears Dak may not play against the Minnesota Vikings on Halloween night.

Per Michael Gehlken of the Dallas Morning News, Cowboys head coach Mike McCarthy sounded as though he was hedging a bit on the prospects of Prescott playing in Week 8.

If Prescott isn't able to go, Cooper Rush would be the starting quarterback for the Cowboys. When asked about that McCarthy said:

“He’ll be ready to go. If he’s up, he’ll be ready to go. We’ve still got some time.”

It's a big time matchup for the Cowboys as they'll be on the road taking on the Minnesota Vikings. Mike Zimmer's squad appears to be far better than the 3-3 record would indicate while Dallas has been red-hot to start the season, sitting at 5-1. A big reason for that has been the play of Prescott.

For what it's worth, Cowboys owner Jerry Jones sounded much more optimistic about Prescott's chances to play on Sunday.

Perhaps there is some miscommunication between McCarthy and Jones or maybe they just have to different outlooks on the situation. Regardless, if Prescott isn't able to go, expect the Cowboys to have an altered blueprint against the Vikings on Sunday night.
