The Cowboys got two offensive linemen healthy this week, but they may have lost one.
Guard Kevin Kowalski left Tuesday’s practice with a leg injury.
Offensive line coach Bill Callahan said after practice he didn’t know how bad the injury was. It’s another challenge for a line that began training camp without last year’s starting guards, Nate Livings and Mackenzy Bernadeau, and a reserve guard, Ron Leary, because of injury.
Kowalksi had worked with David Arkin on the first team until Livings and Leary returned this week. Callahan said Bernadeau, who had offseason shoulder surgery, might be able to go next week.
The Cowboys worked out a guard before Tuesday's practice.
Callahan credited Arkin’s progress for bringing some stability to the line. Arkin has not missed any practice.
“I like the progress that he’s made since he arrived in camp,” Callahan said. “He makes incremental progress. It’s good to see him focus on one technique and get better on a daily basis. I’m really proud of him. He’s worked hard.”
