As of 2022, which boxer holds the record for the most consecutive knockouts (including unsanctioned bouts)?

LaMar F. Clark (December 1, 1934 – November 5, 2006) was an American professional boxer who fought in the heavyweight division. He was active from 1958 to 1961 and fought a recorded 46 times in his 3 year-career, most of which in his home state of Utah. Clark has the current record of most consecutive knockouts at 44 (including unsanctioned bouts). It is still however unclear how the officials of the Utah State Boxing Commission sanctioned most of his bouts versus inexperienced debutants being aware of his knockout-winning streak without ever questioning the level of opposition.

The Guinness Book of World Records credits Clark not only with the most consecutive 44 KOs record, set at Las Vegas, Nevada, on January 11, 1960, but also with the world record for most knockouts at one night for he reportedly knocked out 6 opponents in one night (5 in the first round) at Bingham Canyon, Utah, on December 1, 1958. This helped to put his name not only to the Guinness Book, but in the sports history books as well.
