7.2.1 Name and Number. Each Player will be assigned a number, which will not change throughout the Season. The number will have a maximum of two digits and appear on the back of the jersey and on the left side of the shorts and be current font provided by the league designated supplier (See Exhibit E, "Player Uniform Specifications"). Field player numbers must be whole numbers between “2” and “99” while only goalkeepers may wear numbers “0” and “1”.
7.2.2 Bleeding Player. If a Player is bleeding, he must leave the field immediately to have the bleeding stopped and his skin and uniform cleaned as thoroughly as possible. When the Player is ready to return to the Game, the Referee may delegate responsibility to the Fourth Official to inspect the injured area and the uniform for blood. Once inspected by the Fourth Official, the Player may re-enter the Game with the Referee’s permission. The Player may be required to change his uniform prior to re-entry. Wearing an unnumbered jersey is permitted only under these circumstances. A player will not wear a jersey with another person’s name on it. If necessary, name information will be taped or masked, preferably in the same color as the team uniform. As a last resort, an alternate jersey with another substitute’s player number may be worn only if a) the number is taped or masked, preferably in the same color as the team uniform, and b) the substitutes name will be removed from the team roster (the roster must also be adjusted to show the replacement jersey number for the player now wearing it).
The Equipment Manager will ideally have a second set of uniforms, and at minimum will have several extra jerseys (nameless, at least one with an unused number and at least one without a number, but displaying all Sponsor and League mandated markings) available at the bench.
