The Dallas Cowboys can't catch a break along their battered offensive line.
Left guard Ronald Leary will undergo arthroscopic surgery on his right knee Friday, the team's website reported. The procedure places his status for the season opener against the New York Giants in jeopardy.
Leary was projected to start at left guard, but the job now falls to third-year pro David Arkin. Leary's injury is unrelated to the left-knee issues that scared teams away from drafting him in 2012, but that's where the good news ends for Dallas. The inside of their line is paper-thin and screaming for help.
