In American football and Canadian football, not all players on offense are entitled to receive a forward pass. Only an eligible pass receiver may legally catch a forward pass, and only an eligible receiver may advance beyond the neutral zone if a forward pass crosses the neutral zone. If the pass is received by a non-eligible receiver, it is "illegal touching" (five yards and loss of down). If an ineligible receiver is beyond the neutral zone when a forward pass crossing the neutral zone is thrown, a foul of "ineligible receiver downfield" (five yards, but no loss of down) is called. Each league has slightly different rules regarding who is considered an eligible receiver.
