Nathan Leeson has been fighting bare-knuckle since 2016. During that time he’s gone 4-1-2 and although he hasn’t been the most active during that time, he has won a title and defended it twice - albeit once with a draw. Leeson has scored wins by knockout, decision and made his opponent’s corner throw in the towel.

With a brutal style and a willingness to put on entertaining fights first and foremost, Leeson will more often than not be in a fight that ends with a finish. He was out of action since 2022 but got into a hybrid rules boxing match which has some components of bare-knuckle involved but uses boxing gloves. It should be noted that in his 2026 modified rules bout, he won a title via TKO in round one. Any dust that was settling on his hands was knocked off in his comeback match just four months before his BKFC debut at BKFC 90.
