The match is on.
NJPW officially announced that Jon Moxley will challenge Juice Robinson for the IWGP United States Title at the Best of Super Juniors Final on June 5.
From NJPW:
Jon Moxley, formerly known as Dean Ambrose in the WWE, will be challenging Juice Robinson for the IWGP US Heavyweight Championship at the finals of the Best of the Super Jr. 26 in Ryogoku Sumo Hall. A menacing figure has been interrupting the official tournament matches during the tour in an effort to intimidate the IWGP US Heavyweight Champion. Robinson had been putting a brave face on the situation, reacting with his usual bravado. On night 10 of the tour however, whilst providing commentary for NJPW World, Robinson finally snapped and stormed out the building.
Moxley was later confirmed to be Robinson’s mystery challenger via social media and confirmed his attendance at Ryogoku Sumo Hall on June 5. After a meeting of the IWGP commission, a decision has been made to accept Moxley’s challenge to Robinson. Juice Robinson will attempt to make his 4th defense of his championship during the Best of Super Jr. 26 final night.
This will mark Moxley's first official match since leaving WWE.
