Soccer is the most popular sport in the world although recent studies on concussion incidence are scarce. Here, a nationwide prospective study on concussion incidence, symptom severity, risk factors, gender differences, and return\u2010to\u2010play after concussion was performed in 51 Swedish elite soccer teams during the 2017 season.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>In the 1st and 2nd soccer leagues for men and women, a Sport Concussion Assessment Tool (SCAT)\u2010based questionnaire study was performed at preseason (baseline) and from 48\u00a0hours to 3\u00a0months post\u2010concussion.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>We followed 959 players (389 women, 570 men) for 25\u00a0146 player game hours (9867\u00a0hours for women, 15\u00a0279\u00a0hours for men). Concussion incidence (n\u00a0=\u00a036\u00a0concussions during the season) was 1.19\/1000 player game hours (females 1.22\/1000\u00a0hours, males 1.18\/1000\u00a0hours;<jats:italic>P<\/jats:italic>\u00a0=\u00a0.85).
