It has been something of a roller-coaster couple of years for Jose “Rayo” Valenzuela.

In March 2023, coming off his first career defeat – a third-round knockout to Edwin de los Santos – he lost again, highly controversially, dropping a unanimous but razor-thin decision to Chris Colbert. Nine months later, he was emphatically victorious, knocking Colbert cold with a right hook in the sixth round of a rematch.
