Update: The school has announced the move.
"Today is a difficult day for the Western New Mexico Mustang Athletic Department. Coach Tristan, our Head Football Coach, has decided to move on from WNMU and relocate back to Springfield, MO, area. We have lost a great coach, but more than that, a great person," said AD Scott Noble.
Frank Tristan has resigned as head coach at Western New Mexico, sources told FootballScoop on Wednesday. Sources said Tristan has accepted a high school job.
A formal announcement is expected later today. WNMU is expected to look outside the program for Tristan's replacement.
Tristan has been WNMU's head coach since 2018, going 1-21 during that time. The Mustangs played one game during the 2020-21 academic year, a 31-6 loss to UT-Permian Basin on March 13.
He was previously the head coach at Southwestern Assemblies of God, an NAIA school in Waxahachie, Texas, where he won 20 games in his three seasons leading the Lions.
Western New Mexico is a Division II school in Silver City, N.M. The Mustangs compete in the Lone Star Conference.
Rival Eastern New Mexico will also break in a new head coach this fall after their head coach, Kelley Lee, left to become the head coach at Veterans High School in Brownsville, Texas.
