NFHS - is the pass behind or beyond the line of scrimmage? If so, is it caught by a receiver eligible by both number and by position? If behind the LOS, and the receiver is eligible by both, then no flag - an ineligible receiver can go beyond the LOS on a pass that stays behind the LOS. If beyond the LOS, ineligible downfield. If thrown to an ineligible receiver beyond the LOS, two flags - illegal touching (loss of down) and ineligible downfield. B/R will decline the ineligible downfield, and accept the illegal touching, as it comes with a loss of down, so no replay.
