F. Substitutions
Unlimited substitutions can be made with the referee's consent prior to a throw-in, on a goal kick, after a goal, and at half time. Both teams may substitute prior to goal kicks, after a goal, and at half time. As to throw-ins, however, only the team in possession has the initial option of substituting, but if it does, the other team may also substitute. No substitution is allowed prior to a corner kick. Note: no substitution can be made without the referee's consent.
G. Injuries
If the game is stopped to allow a substitution for an injured player, the other team may also substitute, on a one-for-one basis. If a coach comes on the field to attend an injured player, then the injured player must come off the field.
H. Cautioned Players
A cautioned (yellow-carded) player must leave the field immediately, and a substitute may enter with the referee's consent. If that player's team has no substitutes, his/her team will play short-handed until its next substitution opportunity. If the yellow-carded team's player strength falls below the minimum, the game will still continue.
Note: This BAYS rule for temporarily removing cautioned players is not intended to cause a game forfeit. (also noted in Law 12 C)
