Terence Allan Crawford is an American professional boxer. He has held multiple world championships in four weight classes, from lightweight to light middleweight, including lineal titles in three of those weight classes, the undisputed championship at light welterweight and welterweight—and is one of only three male boxers in history, along with Naoya Inoue and Oleksandr Usyk, to become the undisputed champion in two weight classes in the four-belt era.
