The hits just keep on coming for the Dallas Cowboys at guard this time taking down presumed starter Ron Leary. Earlier tonight Tom Ryle posted the news at BTB about left guard Ron Leary having an MRI on his injured knee. That news has shifted Ron Leary will have his knee scoped on Friday and will miss 2-6 weeks according to a report from the reliable Nick Eatman. This puts his status in doubt for the season opener against the New York Giants on Sept. 8th. The good news if you can have good news is that the injury is not to his knee with the degenerative condition. So there's that. But in the immediate future the Cowboys will have to play a preseason game against the Arizona Cardinals on Saturday with David Arkin likely starting at left guard. Arkin wasn't a total bust earlier in camp when he was starting in front of an injured Mackenzy Bernadeau but he's also not the guy Dallas wants out there while Tony Romo is roaming the backfield.
