Since Week 1 of the high school football season in Southern California, the headlines coming out of Bishop Montgomery High School have somewhat overshadowed the football on the field each Friday night.

More news came out of the Catholic private school Friday afternoon when the CIF deemed 19 football players ineligible to compete in any sport or at any CIF school until 2027. The decision came after Bishop Montgomery's internal investigation which was prompted by a multitude of CIF violations from within the football program, which eventually led to the Archdiocese and school canceling the 2025 varsity football season.

Nevertheless, the show must go on, as they say. Here are the scores and notable stat lines from the Top 25 football teams in the CIF Southern Section from Week 3.
