While the FSYFL does have a slightly different approach to certifications and weigh ins from other leagues, we are extremely strict on our weight and age implementations. Original birth certificates are a requirement of the FSYFL. The weight of a player is certified at the first game of the season, from there on out players are NOT weighed in again for the season. However the teams will be checked in every week to ensure only certified players are playing in the games. For full weigh in rules Click Here.
