Former two division champion Ricardo Mayorga (31-9-1, 25 KOs), who last month was attacked at a gas station in Nicaragua, must be feeling a lot better - because he's back with the verbal attack.
In a video message filmed by former world champion Rosendo Alvarez, Mayorga called for a fight with UFC superstar Conor McGregor.
Mayorga, 44-years-old, has been out of the ring since an August 2015 knockout loss in his rematch with Shane Mosley. He was planning to return to the ring last month in Nicaragua, but the contest never happened.
Last month, McGregor made an unexpected move by obtaining a boxing license in the state of California.
Since 2015, McGregor has discussed the idea of showcasing his skills in a boxing ring, especially in a potential a fight with retired former five division world champion Floyd Mayweather Jr.
Nobody knows if McGregor is actually serious about becoming a boxer and many view his move to get a license to box as nothing more than a publicity stunt.
"McGregor, I admit that he's has been very good at mixed martial arts, but in boxing he is making mistakes ... As soon as I grab him, I'm going to break him down, I'm going to disintegrate him," Mayorga said.
"If you are looking for me, you will find me. I have not fought, as they say, with [scrubs and journeymen], with a ghost record like [McGregor] has. But if he wants to fight and he's looking for me - he's going to find me. Let him tell me when he wants us to fight and where he wants to do it."
"In boxing, when we step in the ring - he's going to know that I'm a man and he's a woman. McGregor is wide open when he fights ... I'm going to lower his jaw to his navel, so he learns to fear me and shows respect."
"I'm going to exterminate that clown fast. He's going to be very sorry, because in the sport of boxing he is not on my level. I do not feel old or defeated. I know I can play with that bearded man ... and I'll send him back to Mixed Martial Arts and that's where he should be."
