IRVING, Texas -- Offensive coordinator/offensive line coach Bill Callahan said Tuesday he will call plays for the Dallas Cowboys in 2013, but head coach Jason Garrett, who has handled those duties since 2007, wouldn't confirm anything.

Owner Jerry Jones created a stir Tuesday when he told reporters a decision on the play caller had been made weeks ago and to watch practice to give them any hints about who it may be.

Confused? Welcome to another day at Valley Ranch where a secret was revealed, only to be bottled up again.

"Well, I'm not assuming anything," Jones said earlier Tuesday when asked if it's safe to assume Callahan would be calling the plays. "I'm just saying, I don't want to say. But the big deal is if you been looking at practice you can get a pretty good idea of how it's going there and you see Bill very involved in what we're doing out there."

Callahan said the last time he called plays he was the head coach at Nebraska.

"I'm flattered and as I said this a long time ago when we were visiting in January and February, everybody has a stake in this," Callahan said.

"It's a compliment to our staff and it tells you the way our guys work on the offensive side of the ball. It's been productive all the way around. I'm really encouraged, I'm honored and just do the best job for our fans and our team."
