IRVING, Texas (AP) -- The Dallas Cowboys are Danny Shelton Youth Jersey running out of chances to stay in contention without Tony Romo, and owner Jerry Jones is running out of optimism. ''To be realistic, it's going to be a daunting task, even with Romo, to get our feet back under us,'' Jones said after the fifth straight loss without his star quarterback, 13-12 to Seattle on Sunday. ''Obviously, we think we'll play better when we get Romo back.'' The problem is, the games might not matter much if Dallas doesn't win now. Even executive vice president Stephen Jones acknowledged not long after Romo broke his left collarbone in Week 2 that the Cowboys would have difficulty defending their NFC East title if they went ''oh-fer'' in seven games without Romo. Dallas (2-5) is down to just two more chances for the elusive win and could really use both, starting Sunday night with division rival Philadelphia and DeMarco Murray.

If they don't beat Philadelphia, the Cowboys' skid will http://www.nflcowboysofficial.com/Authentic-Byron-Jones-Jersey reach six games. It would be their longest losing streak since the 1-15 debacle of 1989, the year Jerry Jones bought the team. But one thing Dallas does have going for it: the other three NFC East teams have four losses. ''Within our division, you have to realize that there is hope,'' said Matt Cassel, who has lost two games filling in for Romo after Brandon Weeden lost the first three starts following the injury. ''There are nine games left, and guys have to realize that and have to understand that you have to come out and continue to compete.'' The only time the Cowboys didn't really have a shot to win was a blowout by undefeated New England. Otherwise, they've had second-half leads in all four games - and critical letdowns at key points from all three phases of the game. Against Seattle, Dallas was held Shane Ray Kids Jersey without a touchdown for the second time in three games after going four years without that happening under Romo. Even when Greg Hardy's interception of Russell Wilson gave the Cowboys the ball at the Seattle 16 in the fourth quarter, they had to settle for a field goal and a 12-10 lead.
