US Soccer, MLS and NWSL to test concussion substitutes

U.S. Soccer, Major League Soccer and the National Women’s Soccer League are joining a trial program to address concussions. Teams will be allowed two additional substitutes for head injuries in each match. The International Football Association Board, which sets the rules for the game, approved the trial for concussion substitutes last December. It is expected to run through August 2022. FIFA is considering whether the concussion rule will be used at the Tokyo Olympics this summer.
