The move prevents Gurode from becoming a free agent.
Gurode was originally a second round draft choice out of Colorado in 2002.
He was named as a Pro Bowl replacement following last season, his first as a fulltime starter at center.
Gurode's back up, one time starter Al Johnson, is also scheduled to become a free agent in March.
Sources close to the Cowboys maintain that Johnson will likely not be re-signed, especially with Gurode's improvement last season.
