SMU head coach June Jones announced in a news release Thursday that assistant coaches Joe Haering and Bob Palcic will not return for the 2013 season. Haering's contract expires in June, at which time he will pursue other opportunities, while Palcic recently announced his retirement.

"I want to thank Joe and Bob for all their work for our program," Jones said. "They were both valuable members of our staff and we wish them the best."

Haering spent four years with SMU as assistant linebackers coach and helped the Mustang reach a school-record four straight bowl games. He had previously spent 12 seasons as a college scout with the Buffalo Bills.

Palcic just completed his first season as offensive line coach with the Mustangs.
