Go ahead and file this story under "just what the Dallas Cowboys DID NOT want to happen in their first preseason game." As first reported on this morning's Dan Patrick Show, Cowboys star tight end Jason Witten will miss the rest of the preseason and possibly more time with a spleen injury. Witten was injured after taking a shot from Oakland's Rolando McClain in the first quarter Monday night. The big question will be whether or not surgery will be required. If no surgery, Witten will miss up to three weeks, but coould be ready by September 5th for the season opener against the New York Giants. If he needs surgery, Witten will be out indefinitely and John Phillips will become the Cowboys' number one tight end. Regardless of the outcome, Tony Romo just lost his favorite target for the rest of the preseason and maybe longer.
