Cowboys still looking for a tailback?

There's a glaring hole still open behind Cowboys quarterback Tony Romo this summer. DeMarco Murray used to be there, but now he's in Philadelphia. Lance Dunbar and Joseph Randle are still around, but Darren McFadden was tagged as the No. 1 after a March trade with the Raiders. 


But injuries to both his hamstrings has largely kept him from his post in the training camp sessions thus far, and the faint sound of grumbling is beginning to be heard from the executive suite.

Ed Werder of ESPN reported "frustration building over injury absence of Darren McFadden and effect having on workload of other running backs" on Twitter on Wednesday.

The relative instability of the Cowboys' backfield has driven team vice president to start speculating if they did enough to replace last season's league-leader in yards and touchdowns.

"We would have liked to have added a running back to that group," he told Tim Cowlishaw of the Dallas Morning News. "The situation didn't present itself in the draft, so we didn't get that done. We probably missed out there. On executing a plan, if you didn't execute one part of it, that was probably it."

Jones didn't rule out that the team's search for a run game was over.

"There's backs out there that I think still have some gas left in the tank, and if we need to go get one, we'll go get one."

The sooner, the better.
