SUBJECT: PARTICIPATION OF JUDOKA IN OTHER COMBAT SPORT INTERNATIONAL COMPETITION
Any Judoka classified in the ((IJF rankings list)) is not authorized to take part in any international competition of any combat sport, other than Judo, unless specific authorized by IJF.
Would Kano be pleased with this? Waiting for Travis Stevens to say something...
