In 2019, five years from his last official bout points defeat to Floyd Mayweather in the MGM Grand of ] Las Vegas Marcos "Chino" Maidana announced that would fight again . He had officially retired in 2016, with a letter expressing his intention to focus on his boxing promotion company Chino Maidana Promotions after a long time out of the ring. But something told him he still had boxing in him, and so he flew back to Prince Ranch in Las Vegas to prepare.
He had signed by three fights with Premier Boxing Champions the company of Al Haymon representative of Mayweather. The physical preparation in Las Vegas promised to be intense, especially for someone who had spent five years without fighting and who was known to have difficulties giving weight. Already in the final stages of his demanding exercise plan, Maidana warned: "I do not want to go wrong and be a role." A week later in April 2019, he abruptly returned to the country and announced his definitive retirement .
Thus, the return of one of the last Argentine boxers to face face to face with the elite was frustrated. Maidana is the only one to have fought twice with Floyd Mayweather, considered the best pound for pound of all time ( Gustavo Cuello Carlos Ríos and ] Carlos Baldomir did it once). But just seven months later and to everyone's surprise, El Chino announced a final exhibition match : he would fight Jorge "Acero" Cali former kickboxing champion , in April of this year.
