It has been hypothesized that futsal's format of a smaller field and fewer players might mean that players are exposed to fewer head contact events than those reported in football. Our objective was to analyze the incidence and characteristics of headers, head impacts, and potential head injuries in one men's international futsal tournament. In this cross\u2010sectional video analysis study, all head contact events (including headers, head impacts, and potential head injuries) from all 52 matches of the FIFA Futsal World Cup Lithuania 2021 were analyzed. There were 1065 head contact events with an incidence rate (IR) of 3014\/1000 match hours (MH), including 839 headers (IR2376\/1000MH). The most frequent head impact was upper\u2010limb\u2010to\u2010head impacts (\n                    <jats:italic>n<\/jats:italic>\n                    \u2009=\u2009106, IR300\/1000MH) and the least frequent was head\u2010to\u2010head impacts (\n                    <jats:italic>n<\/jats:italic>\n                    \u2009=\u20098, IR 23\/1000MH). There were 38 potential head injuries (IR108\/1000MH) primarily from upper\u2010limb\u2010to\u2010head impact. There was a statistically significant relationship between pitch location and type of head contact event (Cramer's\n                    <jats:italic>V<\/jats:italic>\n                    0.18,\n                    <jats:italic>p<\/jats:italic>\n                    \u2009=\u2009&lt;\u20090.001), with most events occurring outside the penalty areas (83.4%). Headers were the most common head contact event in the FIFA Futsal World Cup, with an IR similar to that reported in football. Although upper\u2010limb\u2010to\u2010head impacts were the primary cause of potential head injuries in both futsal and football, head\u2010to\u2010head impacts were less common in futsal.\n                  <\/jats:p>","DOI":"10.1111\/sms.70083","type":"journal-article","created":{"date-parts":[[2025,5,30]],"date-time":"2025-05-30T00:13:31Z","timestamp":1748564011000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Incidence of Head Contact Events Including Headers, and Potential Head Injuries at the\n                    <scp>FIFA<\/scp>\n                    Futsal World Cup Lithuania 2021"],"prefix":"10.1111","volume":"35","author":[{"given":"Ayda","family":"Sarkohi","sequence":"first","affiliation":[{"name":"Medical Faculty, Link\u00f6ping University  Link\u00f6ping Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alice","family":"Hovenberg","sequence":"additional","affiliation":[{"name":"Medical Faculty, Link\u00f6ping University  Link\u00f6ping Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6883-1471","authenticated-orcid":false,"given":"Martin","family":"H\u00e4gglund","sequence":"additional","affiliation":[{"name":"Unit of Physiotherapy, Department of Health, Medicine and Caring Sciences Link\u00f6ping University  Link\u00f6ping Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4308-901X","authenticated-orcid":false,"given":"Andreas","family":"Serner","sequence":"additional","affiliation":[{"name":"FIFA Medical, F\u00e9d\u00e9ration Internationale de Football Association  Zurich Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2194-3353","authenticated-orcid":false,"given":"Kerry","family":"Peek","sequence":"additional","affiliation":[{"name":"FIFA Medical, F\u00e9d\u00e9ration Internationale de Football Association  Zurich Switzerland"},{"name":"Sydney School of Health Sciences, Faculty of Medicine and Health The University of Sydney  Sydney New South Wales Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,5,29]]},"reference":[{"key":"e_1_2_12_2_1","volume-title":"About Futsal","author":"United States Youth Futsal"},{"key":"e_1_2_12_3_1","doi-asserted-by":"publisher","DOI":"10.1136\/bjsports-2016-097217"},{"key":"e_1_2_12_4_1","doi-asserted-by":"publisher","DOI":"10.1055\/a-0808-2551"},{"key":"e_1_2_12_5_1","doi-asserted-by":"publisher","DOI":"10.1097\/JSM.0000000000000572"},{"key":"e_1_2_12_6_1","doi-asserted-by":"publisher","DOI":"10.1080\/15438627.2024.2324257"},{"key":"e_1_2_12_7_1","doi-asserted-by":"publisher","DOI":"10.1136\/bjsm.2010.076752"},{"key":"e_1_2_12_8_1","doi-asserted-by":"publisher","DOI":"10.5114\/hm.2019.83994"},{"issue":"1","key":"e_1_2_12_9_1","first-page":"14","article-title":"Contributions Agility, Resilience and Self\u2010Confidence Against Ball Dribbling Skills (Dribbling) Futsal","volume":"9","author":"Darmawan F.
