Tim Tszyu had a great year. He fought three times in his native country Australia and won all three, including a first-round knockout of Carlos Ocampo in June. He was successful, yes, but 2023 hasn’t gone as he planned. Tszyu was supposed to challenge Jermell Charlo — the undisputed super welterweight champion at the time — for his four titles on Jan. 28, but Charlo fractured his left hand while training and the fight was postponed.
