Dallas Cowboys offensive coordinator Bill Callahan is expected to leave the NFC East champions due to heavy interest from other NFL teams in his services as an offensive coordinator and offensive line coach.

He's being replaced by Scott Linehan, the Cowboys' new offensive coordinator.

Last year, Linehan called the plays. However, he had the title as passing game coordinator.

Callahan did a great job for the Cowboys with their running game and offensive line.

Now, he's looking to move on.
