Sefer Seferi

Seferi made his professional debut in May 2007 in the cruiserweight division. Over the next 9 years he built up a record of 21–0 with 19 knockouts, albeit against low level opposition.

On 17 September 2016, Seferi fought former WBC heavyweight title challenger and future WBA heavyweight champion Manuel Charr for WBA International heavyweight title, with Seferi making the step up to heavyweight for the first time. Charr defeated Seferi by unanimous decision after 10 rounds, ending Seferi's unbeaten record.^[2]

On 20 May 2018, Seferi was announced as the first opponent for the return of former unified and lineal heavyweight champion Tyson Fury, with the fight set to take place on 9 June at Manchester Arena. The fight would be Fury's first since he beat Wladimir Klitschko to become champion more than two and half years previously in November 2015.^[3][4] In April 2018, several weeks before Fury's opponent was announced, several press outlets reported Seferi was rumoured to have been chosen, with Seferi himself quoted as saying, "This would make my dream come true. I never thought I'd have the chance to stand against Fury, he is my idol. Fury is a boxing legend of the 21st century. He is tall, has weight and strength but moves easily, and he dethroned Klitschko. Fury is a bear."^[5] The fight ended in a disappointing fourth round corner retirement loss for Seferi.^[6]

On 21 September 2019, he challenged Kevin Lerena in Gauteng, South Africa for his IBO cruiserweight title, but was unsuccessful and lost via third-round technical knockout.^[7]
