Gibbs was defensive coordinator at LSU last season, helping the Tigers win the Southeastern Conference.
He had the same job at the University of Georgia the previous season.
Gibbs is the second coach to come to Dallas in the last 10 years with Oklahoma ties. He took over the Sooners' program in 1989 after Barry Switzer's departure. He led OU to three bowl games, including victories in the 1991 Gator Bowl and 1993 John Hancock Bowl. He had an overall record of 44-23-2.
This time Gibbs replaces George Edwards, who spent four years with the Cowboys before leaving to coach the linebackers for the Redskins under new defensive coordinator Marvin Lewis.
Gibbs was a linebacker at Oklahoma from 1972 to 1974 and played on Sooner squads that ranked No. 1 in the nation in 1974, No. 2 (1972) and No. 3 (1973). He earned his undergraduate degree from Oklahoma in 1974 and his master's degree from his alma mater in 1976.
