Not only can the Japanese welterweight not remember his brutal KO loss to Brian Norman Jr. on Thursday for the WBO world title, but he also cannot recall anything that happened this past month or for the majority of May either.

Jin Sasaki has no memory of the night he attempted to make history as the first Japanese boxer to win a welterweight world title.

Brian Norman Jr. retained his WBO welterweight title with a fifth-round knockout of Japans Jin Sasaki in Tokyo. Following the defeat, Sasaki was hospitalized and revealed memory loss spanning six weeks.
