Left guard Kyle Kosier has limped off the practice field, making it two hobbled offensive linemen this week for the Dallas Cowboys.
Cowboys coach Wade Phillips was expected to give details about
the injury at his afternoon news conference. Dallas also has a
second practice later Tuesday.
Veteran Montrae Holland took Kosier's place during the morning
workout and would start if Kosier doesn't return for the preseason
game Saturday night in San Diego.
Offensive coordinator Jason Garrett said missing two starters
will be a factor in deciding how long Tony Romo plays against the
Chargers, or if he plays at all.
Right tackle Marc Colombo went down Sunday and had arthroscopic
knee surgery Monday. He's expected to return for the season opener.
