New Japan Pro Wrestling recently announced that Jon Moxley will be competing in the G1 Climax tournament scheduled for Dallas on July 7th, but will be joining the tour when it returns to Japan on July 13th.
The reason Moxley won't be in Dallas is that AEW is not allowing Ambrose to work NJPW shows in the United States, that is the deal Ambrose signed when he joined the newly formed promotion.
"Jon Moxley’s deal is AEW has his rights in the United States,” Dave Meltzer said. “He’s free to work New Japan when it doesn’t conflict with AEW and he’s allowed to be in the G1, it’s fine but not US shows. AEW didn’t allow for that."
