According to information circulated by World Boxing Council President Mauricio Sulaiman, former world champion Moises Fuentes, 37-years-old, passed away on Thursday morning - more than a year after being hospitalized for a brain injury.

In October of 2021, Fuentes snapped a layoff of over three years - to face undefeated puncher David Cuellar in Cancun. Fuentes suffered brutal knockout loss in six rounds. Fuentes was already coming off back-to-back knockout defeats to Daigo Higa and Roman Gonzalez.

After his most recent defeat, Fuentes was taken out on a stretcher and quickly transported to a hospital in Quintana Roo. A severe clot in the brain was discovered and he underwent emergency surgery.

The surgery saved his life, but Fuentes was never the same and had to deal with numerous health complications that affected his quality of life.

“Thank God, Moises Fuentes is already resting in peace. A warrior who fought to the last breath. Our condolences to his family and friends and our appreciation to his wife for her dedication and dedication with indescribable love during this difficult year of suffering. May he rest in peace,” Sulaiman wrote through his social networks.

Fuentes has eight world championship fights. In 2011, he captured the World Boxing Organization minimumweight world title by defeating Raúl García. He would also pick up a stoppage win over Puerto Rican legend Iván Calderón in a world title defense. In 2013, Fuentes won the interim-WBO junior flyweight title.

In his 33 professional bouts, Fuentes won 25 and 14 of them by knockout. He had one draw and suffered seven defeats.
