Ron Leary started all 16 games at left guard last season, but he trails Mackenzy Bernadeau in the battle for the starting job. Leary missed the first six practices after straining his hamstring in a non-sanctioned conditioning test last week.

“Ron has played a lot of football for us, and he’s still a young player who needs a lot of snaps,” Cowboys coach Jason Garrett said. “We’re disappointed he hasn’t been able to get them this first week of camp, but he’ll be back out there.

“There’s a lot of football to be played before this preseason game and really throughout the preseason, so there’s plenty of opportunity for him to show up in this competition.”
