Mexican WBA & WBO cruiserweight champion Gilberto "Zurdo" Ramirez (47-1, 30 KOs) will face Cuban power puncher Yuniel Dorticos (27-2, 25 KOs) in his next fight.
The bout is scheduled for June 28, though the venue has yet to be determined.
In November, Ramirez secured a unanimous decision victory over Chris Billam-Smith, unifying the division's titles.
Meanwhile, Dorticos returned to the ring in June after a 1.5-year layoff, knocking out Alan Campa in the first round.
