Pop Warner Youth Football Rules
The two San Diego County Football Conferences (San Diego and Palomar) are governed by two different groups. San Diego (south county) is now American Youth Football and they will use the National High School Federation Rule Book as modified by the American Youth Football Rules below. Palomar (north county) is still associated with Pop Warner. Although their coaches have the Pop Warner Rule Book, they still use the modifications set forth below.
