MERIDIAN -- Rocky Mountain head football coach Scott Criner has resigned.

Criner, who led the Grizzlies to their first 5A state football championship in 2015, went 40 and nine in his five seasons as head coach. He was also named Coach of the Year.

Before becoming the head coach at Rocky Mountain, Criner was an assistant coach at Eagle for five years. During that time, Criner coached players like quarterback Taylor Kelly (ASU) and quarterback Tanner Mangum (BYU).

Criner helped the Mustangs to three state championship appearances, one semi-final appearance and one quarterfinal appearance.

The Mustangs won the 5A state title in 2009.

KTVB Sports Director Jay Tust says Criner will replace current Eagle High Athletic Director Kimber Chrz, who will become a vice principal.

Official practices begin August 7th.

No word on who will replace Criner.
