The Cowboys hired Bob King as a defensive assistant replacing Dat Nguyen who left the organization earlier this month according to a source.
King was a defensive line coach at West Texas A&M for two seasons. Prior to that, King was a defensive line coach at Baylor, working with the tackles in 2006 and 2007.
The Cowboys have now completed their coaching staff.
There were four coaches with expiring contracts and Todd Grantham and Nguyen choice to go elsewhere.
Grantham became the defensive coordinator at Georgia and Nguyen left the Cowboys without a job in hand.
But he was soon hired by Texas A&M as their linebackers coach, which was announced last weekend.
