Oxnard, CA (Sports Network) - The Dallas Cowboys announced Friday that guard Nate Livings is scheduled to undergo a scope on his ailing right knee, a procedure that could put his status for the season opener in question.
Livings, a 16-game starter at left guard last year, had surgery on the same knee in February and had just returned to practice after missing some time with a cut on his foot.
The seven-year veteran, who signed a five-year, $18.7 million free-agent deal with Dallas prior to last season, is expected to be sidelined anywhere from 2- to-4 weeks. The Cowboys begin their regular season Sept. 8 against the New York Giants.
Livings' injury is the latest blow to a Dallas offensive line that's had several members down during camp. Right guard Mackenzy Bernadeau remains on the active/physically unable to perform list due to a hamstring strain, while reserve guards Ryan Cook (back) and Kevin Kowalski (knee) and tackles Jermey Parnell (hamstring) and Demetress Bell (conditioning) are not currently practicing as well.
