U.S. Soccer, Major League Soccer and the National Women's Soccer League are joining a trial program that will allow teams two additional substitutes for suspected concussions in each match. The International Football Association Board, which sets the rules for the game, approved the trial for concussion substitutes last December. U.S. Soccer is working with the top men's and women's leagues, as well as the United Soccer League and the National Independent Soccer Association, to implement the pilot program protocol across the sport in the United States. If teams sub out a player because of concussion, the opposing team gets an additional sub — addressing competitive balance concerns. Additionally, different cards will be used by officials during MLS matches to indicate the kind of substitution being made: White for a normal sub, pink for a concussion sub and blue for an additional sub.
