3-7-1 "Between downs any number of eligible substitutes may replace
players. Replaced players shall leave the field immediately."
2-32-15 "A substitute is a team member who may replace a player or fill a player vacancy. A substitute becomes a player when he enters the field and communicates with a teammate or an official, enters the huddle, is positioned in a formation or participates in the play. An entering substitute is not considered to be a player for encroachment restrictions until he is on his team’s side of the neutral zone. A team member entering the field to fill a player vacancy remains a substitute until he is on his team’s side of the neutral zone."
2-32-12 "A replaced player is one who has been notified by a substitute that he is to leave the field. A player is also replaced when the entering substitute becomes a player."
