Cowboys owner Jerry Jones said today that the Cowboys won’t reveal whether or not Tony Romo can play Sunday until they turn in their list of inactive players on Sunday morning.

Jones said Romo is loosening up his back today and looks OK, but we’ll have to wait until we see whether Romo’s name is on the inactive list before kickoff to learn whether Romo or Brandon Weeden is the starter.

“He’s moving around, been in the meetings today,” Jones said on KRLD. “We make that decision at game time when it’s day to day. We turn that in, obviously you’ve got your 53-man roster and you’ve got to turn your actives in within an hour before the game, and that’s when you’ll know.”

Jones referenced his “Dr. Jones” nickname and said that he’s not involved with the decision, and all he knows is what he hears from Romo and the team’s medical staff. But Jones also hinted that the Cowboys may be purposely vague because they want the Cardinals to have to prepare for both Romo and Weeden.

“The more you can make that other thing cover preparation, cover different possibilities, I think that is a good thing,” Jones said.

It may be a good thing for the Cowboys to make the Cardinals guess. It won’t be a good thing for the Cowboys to be without Romo — or with a Romo who’s less than 100 percent healthy — when they take on the team with the best record in the NFC.
