Major League Soccer announced Monday that its teams will “participate in FIFA’s concussion substitute pilot program,” according to a release. Teams will be able to make up to two concussion substitutes per game, regardless of how many substitutions have already been used up until that point.
MLS clubs will now have two more substitutes available for suspected head injuries.
