He may have wrestled up the first year he was at 14 and under and was actually only in the 12 and under age bracket. I don't think there is anything wrong with that, unless for some strange reason it is stated in the rules that a wrestler can't wrestler up at subs, disrict, state. (I don't think so though, because of the six and under wrestlers who wrestle 8 and under.)

The divisions are 8 and Under, 9 & 10, 11 & 12, 13 & 14, and 15 & 16.
