LAS CRUCES, N.M. (AP) - New Mexico State football coach DeWayne Walker has stepped down after four losing seasons to take a job as an assistant with the Jacksonville Jaguars.

Athletics director McKinley Boston announced Thursday that Walker is leaving to become defensive backs coach for the NFL team.

Walker went 10-40 with the Aggies. He was hired in December 2008, after serving as an assistant at UCLA for three years. Walker has NFL jobs on his resume. Before his time at UCLA, he was an assistant with the Washington Redskins and New York Giants from 2002-05.

Walker never won more than four games in a season with New Mexico State.

The school has not announced plans on its search for a new coach.
