Dave Meltzer noted on the latest Wrestling Observer Radio that NJPW prevented Will Ospreay from working with MLW on a Mexico tour.
The reason for that is due to AAA talent working on the tour. Konnan, who is the booker of AAA and a talent for MLW.
NJPW has a working relationship with CMLL, who are rivals of AAA in Mexico.
