His possible first round opponent was not so sure Emerson should be celebrating.
"It's a case of be careful what you wish for, but I'm genuinely happy for him," Adesanya said. "It's good for New Zealand boxing and James can stop crying about it and get on with the business of training."
Emerson is not a fan of film study and trains one-on-one with his brother-in-law in a simple garage containing punching bags, pads, a speed ball and a chin-up bar. "I always try to keep myself active. Ideally it would have been good to know I was in eight weeks ago but it is what it is. I feel really privileged to be on the card, it's a great benchmark for myself and not many people get these opportunities.
"I'm definitely a major underdog in this tournament ... but anyone has a chance if they've got the heart."
The inclusion of Emerson and Ghanaian Joseph Kwadjo gives the tournament a real international flavour, with New Zealanders Adesanya, Lance Bryant (3-0) and Monty Filimaea (9-10-1), Samoa's Vaitele Soi (22-0) and Australians Brad Pitt (15-1) and Daniel Ammann (29-7-1) completing the card.
Fighters will meet over three three-minute rounds.
