The Cuban Sports Institute reported the information on Thursday.
Ramirez, 24, won a bantamweight gold medal in the 2016 Olympics in Rio, and a flyweight gold medal in the 2012 games in London. He beat Shakur Stevenson in the final round of their 2016 games.

It's not clear what Ramirez plans to do. In previous interviews, he discussed the intention to fight for Cuba in the 2020 Olympics - but now it appears that he's likely going to turn pro.
Cuba has won more Olympic gold medals in boxing than any other country.
In March, the Cuban team suffered another big hit with flyweight Joahnys Argilagos, 21, running away from the team during a tournament in Mexico.
In the past, Cuban boxing champions who defected to compete professionally included Guillermo Rigondeaux, Erislandy Lara and Luis Ortiz.
