According to sources, an assistant football coach with the Diamond Ranch football team resigned in the wake of last week’s brawl against Diamond Bar that resulted in CIF suspending 19 players for Diamond Ranch for Friday’s game against Rowland. Diamond Bar will have to forfeit its next game, also vs. Rowland, which was scheduled Nov. 1. In addition to the dismissal of an assistant coach, Diamond Ranch also suspended some players from school for last week’s brawl, according to sources.
