Usman said it was a trip he had already been planning on making, and having both titleholders make the journey over would only do more for the sport.
The major sporting codes like football, the country's national sport, and basketball were the most popular when Adesanya was growing up, but to see two world champions of Nigerian heritage would open more than a few eyes to the potential in mixed martial arts, Usman believed.
"It's going to raise the profile big time," he told the Herald.
"This is a sport that we can all do. This is not something that requires going overseas for a higher education or things like that, it's something for all. For us to both go back and show them that, hey, you can be victorious and be a champion in this, it's going to be huge."
Since it was established in 1993, the UFC has never taken an event to an African nation. It's something that Usman believed wouldn't take much work, and with the likes of featherweight Sodiq Yusuff (Nigeria) and heavyweight Francis Ngannou (Cameroon) also rising through the rankings, that could come sooner rather than later.
"Israel goes out and does his job, Francis is on the cusp of it; it's inevitable," Usman said.
"I mean, we have tons of Africans now in the sport that are making big strides, so it won't take much."
