RANCHO SANTA MARGARITA (CBS) — An Orange County high school football coach has been placed on administrative leave, according to local Catholic church officials.

Harry Welch was placed on leave Thursday when the Arch Diocese of Orange was notified of allegations involving the varsity football coach.

According to the Los Angeles Times, the high school “received an anonymous email alleging that a player had been pushed or shoved by a coach.”

Orange County authorities are still trying to determine if a crime took place. No criminal complaint has been filed,sheriff’s officials said.

Welch will remain on leave pending a review by both the Santa Margarita administration and the Diocese of Orange, Diocese spokesperson Stephen Bohanon said.

Welch led the Santa Margarita Eagles to the 2011 CIF Division I Championships in December where they defeated Bellarmine Prep of San Jose 42-37.
