Romo joke aside, Cowboys' injury problems at guard getting serious, forcing team to seek help

Tony Romo drew plenty of laughs when he joked on the first day of training camp that his offensive line looked good "running up and down the sideline."

It's getting to the point where it's not funny for the Dallas Cowboys.

Dallas has had injury problems at guard since training camp started more than two weeks ago. And now the Cowboys are in serious pursuit of a veteran.

A day after tentatively agreeing to a deal, former New York Jets guard Brandon Moore told the Cowboys on Wednesday he was retiring.

Last year's starting guards, Nate Livings and Mackenzy Bernadeau, have missed significant time at camp. Romo could have two new starting guards for the second straight year, not to mention a rookie center.
