Cowboys Pro Bowl center Andre Gurode said he had surgery on his right knee in late June.
The Cowboys open training camp Wednesday in San Antonio with a series of meetings and conditioning drills.
Gurode said he had arthroscopic surgery on the knee and just started running three weeks ago. He will be placed on the Physically Unable to Perform list when training camp starts. He will rehab the knee during the early stages of practice.
Gurode, a five-time Pro Bowler, hasn't missed a start the last three seasons and it doesn't appear as if he will miss any regular-season games.
