The Fédération Internationale de Football Association (FIFA) has long had a policy that players who show signs or symptoms of a concussion should have a timely evaluation by a licensed clinician using established assessment tools and should not return to play if a concussion is diagnosed.1 After discussions about poor adherence to this policy in the 2014 World Cup, which were highlighted in JAMA,2 the FIFA Medical Committee made 3 changes to their concussion protocol (Box).3 In this analysis, the incidence, characteristics, and assessment of head collisions during the 2018 World Cup were reviewed to assess compliance with FIFA’s updated concussion protocol.
