Cowboys lose Dat Nguyen

MOBILE, Ala. - Dat Nguyen, the Cowboys assistant linebackers/defensive quality control coach, is not with the rest of the coaches at the Pro Bowl in Fort Lauderdale, Fla.

Nguyen has told Cowboys owner/general manager Jerry Jones he will not return to the coaching staff. Nguyen was in the last year of his deal, but decided to move on, according to a source.

Jones said last week he wanted to retain the three assistant coaches, Brett Maxie, Wes Phillips and Nguyen, who's contracts were expiring. Maxie and Phillips were signed through 2011.

Nguyen has been with the Cowboys as a coach since 2007. He also played for the team from 1999-2005 before retiring due to injuries.

He was a popular player in college at Texas A&M where he led the Aggies in tackles for four straight seasons.
