You must wrestle in your age group in qualifying tournaments. IE. subs, districts and state. I appears the infraction was when he was in the 12U age group. It has been this way for a long time. It has been this way at least 7 years because a thirteen year old (12u age group) who was confused about the cutoff date after moving here from Oklahoma wrestled 14u at state. We did not say anything, it was an honest mistake and it cost a kid from our club a place.
By the way, wrestling is like the only kids' sport you do not have to provide age documentation. All baseball and football at least for the sports I am familiar with.
