BOONE, N.C. -- Jason Capel has been let go after four seasons at Appalachian State.

Athletic director Charlie Cobb said Monday that the school will not renew his contract.

Capel is in the final year of a four-year deal that expires at the end of March. The former North Carolina player -- whose brother Jeff is on Duke's staff -- was the youngest coach in Division I when he was hired in 2010.

The Mountaineers went 9-21 this season, were 5-11 in their final season in the Southern Conference and were eliminated in their league tournament opener by Samford. They went 53-70 in four seasons under Capel.

Appalachian State joins the Sun Belt next season and Cobb said, "We have decided to do so with new leadership."

Capel was 30 years old when he was promoted in April 2010 to replace Buzz Peterson after he left for UNC-Wilmington.

Capel led Appalachian State to a 16-15 record in his first season in 2010-11 but followed that with three consecutive losing seasons. His teams went 32-38 in SoCon play.

The school says its search for Capel's replacement will begin immediately.
