The revised edition of the USSF publication, Guide to Procedures
for Referees, Assistant Referees and 4th Officials, has two changes
in the 2009-2010 edition:
- Page 37 (Penalty Kick, Indicated By The Assistant Referee).
The fourth bullet point has been modified as follows: “If referee stops
game, assistant referee first indicates penalty kick by holding flag
across the lower body and then begins walking toward the corner flag
- Page 40 (Substitutions, Referee procedure). The first bullet
point has been modified to be consistent with International Board
guidelines mandating the use of the whistle to restart play after the
referee has delayed the restart for a substitution. The revised bullet
item now makes it clear that a whistle is required in all such cases.
