A retrospective review of several online NFL player registries identified 31 Achilles tendon ruptures in NFL players between 1997 and 2002. Nineteen percent of injuries occurred during preseason play, while another 18% occurred during the first month of the official season. There was a postinjury reduction of 88%, 83%, and 78% in power ratings for wide receivers, running backs, and tight ends, respectively, over a 3-year period. There was a 95%, 87%, and 64% postinjury reduction in power ratings for linebackers, cornerbacks, and defensive tackles over a 3-year period. On average, players experienced a greater than 50% reduction in their power ratings following such an injury. Thirty-two percent (n = 10) of NFL players who sustained an Achilles tendon rupture did not return to play in the NFL.<\/jats:p>","DOI":"10.1177\/1938640009351138","type":"journal-article","created":{"date-parts":[[2009,10,14]],"date-time":"2009-10-14T00:20:07Z","timestamp":1255479607000},"page":"283-286","source":"Crossref","is-referenced-by-count":131,"title":["Epidemiology and Outcomes of Achilles Tendon Ruptures in the National Football League"],"prefix":"10.1177","volume":"2","author":[{"given":"Selene G.","family":"Parekh","sequence":"first","affiliation":[{"name":"North Carolina Orthopaedic Clinic, Division of Orthopaedic\rSurgery, and Fuqua Business School, Duke University, Durham, North Carolina,"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"suffix":"III","given":"Walter H.","family":"Wray","sequence":"additional","affiliation":[{"name":"Division of Orthopaedic Surgery, Duke University Medical\rCenter, Durham, North Carolina"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Olubusola","family":"Brimmo","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Saint Louis University\rSchool of Medicine\/St Johns Mercy Medical Center, St Louis, Missouri"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Brian J.","family":"Sennett","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, University of Pennsylvania\rSchool of Medicine, Philadelphia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Keith L.","family":"Wapner","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, University of Pennsylvania\rSchool of Medicine, and Pennsylvania Hospital, Philadelphia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2009,10,13]]},"reference":[{"key":"atypb1","doi-asserted-by":"publisher","DOI":"10.1016\/S0278-5919(20)30956-X"},{"key":"atypb2","doi-asserted-by":"publisher","DOI":"10.1177\/036354657700500606"},{"key":"atypb3","doi-asserted-by":"publisher","DOI":"10.1177\/036354658901700305"},{"key":"atypb4","doi-asserted-by":"publisher","DOI":"10.3109\/17453679608996672"},{"key":"atypb5","doi-asserted-by":"publisher","DOI":"10.1177\/03635465020300022501"},{"key":"atypb6","doi-asserted-by":"publisher","DOI":"10.1097\/01.jsm.0000165347.55638.23"},{"key":"atypb7","doi-asserted-by":"publisher","DOI":"10.1097\/00002281-200103000-00009"},{"key":"atypb8","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-0838.1997.tb00126.x"},{"key":"atypb9","doi-asserted-by":"publisher","DOI":"10.2165\/00007256-199418030-00004"},{"key":"atypb10","volume-title":"Defensive player statistics","author":"Sports Illustrated.","year":"2006"},{"key":"atypb11","volume-title":"NFL gamebook, weather, and play-by-play","author":"NFL.com.","year":"2006"},{"key":"atypb12","volume-title":"NFL injury list","year":"2006"},{"key":"atypb13","volume-title":"Offensive Player Statistics","author":"Pro-Football-Reference.com.","year":"2006"},{"key":"atypb14","volume-title":"Official NFL injury list","author":"Kffl.","year":"2006"},{"key":"atypb15","volume-title":"Player registry","author":"Pro-Football-Reference.com.","year":"2006"},{"key":"atypb16","volume-title":"Weather","author":"Old Farmer\u2019s Almanac.com.","year":"2006"},{"key":"atypb17","volume-title":"Power ratings","author":"Athlonsports.com.","year":"2006"},{"key":"atypb18","volume-title":"NFL news","author":"NFL.com.","year":"2006"},{"key":"atypb19","doi-asserted-by":"publisher","DOI":"10.1177\/0363546506290186"}],"container-title":["Foot &amp; Ankle Specialist"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/1938640009351138","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/1938640009351138","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,28]],"date-time":"2026-04-28T21:32:43Z","timestamp":1777411963000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/1938640009351138"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2009,10,13]]},"references-count":19,"journal-issue":{"issue":"6","published-print":{"date-parts":[[2009,12]]}},"alternative-id":["10.1177\/1938640009351138"],"URL":"https:\/\/doi.org\/10.1177\/1938640009351138","relation":{},"ISSN":["1938-6400","1938-7636"],"issn-type":[{"value":"1938-6400","type":"print"},{"value":"1938-7636","type":"electronic"}],"subject":[],"published":{"date-parts":[[2009,10,13]]}}}
