Morocco winger Nordin Amrabat was concussed during the World Cup but played five days laterFootball needs new rules regarding concussion, and should change the way substitutions are used so doctors have more time to assess players, Uefa says. European football's governing body has now requested that Fifa review the current concussion protocol. Current Fifa guidelines suggest a minimum rest period of six days after a concussion - but the final decision rests with team doctors. A report from the New York Hospital for Special Surgery in November 2018 found concussion protocols in football were "ineffective" in almost two thirds of matches at the 2018 World Cup. Last year it emerged after the Champions League final that Liverpool goalkeeper Loris Karius had played the full match despite sustaining a concussion.
