Defection
In March 2018, Argilagos failed to appear at a weigh-in during a tournament in Tijuana. It was thought that Argilagos had defected from Cuba to become professional, following the likes of Luis Ortiz, Guillermo Rigondeaux and Yuriorkis Gamboa who had all previously defected from Cuba and later became professional.
