OXNARD, Calif. -- The Dallas Cowboys are without two interior offensive linemen, Kevin Kowalski and Bill Nagy, because of injuries. Kowalski has a bruise near his ankle and Nagy has a high-ankle sprain on the same leg he fractured last year.
Cowboys executive vice president Stephen Jones said he doesn't believe either player will return this training camp and their long-term status is in question.
"I will say, I am concerned about those two," Jones said. "I don't think they'll be available to start the year more than likely."
Kowalski was supposed to compete for the center job with Phil Costa but his injury has almost eliminated that possibility. Nagy, a seventh-round pick last year, started four games in his rookie year before suffering a fractured ankle at New England.
"Leary is doing a nice job for a guy to come in here from a position change, a left tackle in college (to guard)," Jones said. "Very impressed with him. Done a really nice job. Him and Arkin are getting a lot of reps."
