Floyd Mayweather is set to put on the gloves once again, but it is not in the format that his legion of fans have been accustomed to.
Mayweather is set to take on Japanese kickboxer Tenshin Nasukawa on New Year's Eve in Tokyo.
As soon as the surprise fight was announced, fans began to speculate on the potential rules and conditions that will be in place, although all parties have so far remained tight-lipped on exactly what kind of spectacle to expect.
Nevertheless, a few details appear to be emerging according to Boxing Scene.
They have reported that the New Year's Eve clash will be in a boxing exhibition - so no MMA hybrid rules will be in place.
It is also claimed the bout may only be scheduled for three rounds, meaning regardless of the result, Mayweather's overall record (50-0, 27 by KO) will be untarnished.
American fans can take some respite knowing it is not scheduled to be on pay-per-view in the US, however.
Because of the timing of the fight (Monday morning US time), it will be hard to sell it to the American audience as Japan is 14 hours ahead of the East Coast and 17 hours ahead of Pacific Standard time.
If it stays like that, it will be the first time that a Mayweather fight has not been available on pay-per-view since 2005 when he fought Sharmba Mitchell.
In Japan, the fight will air on Fuji TV.
While it isn't an official fight, Mayweather is unlikely to overlook his opponent, who is 21 years his junior.
Not only is Nasukawa a much younger man, he is also very good at his craft compiling a 27-0 record (20 by KO).
Nevertheless, Mayweather will still be the heavy favourite as he has a clear weight and height advantage.
