Israel Adesanya, Brad Riddell and Carlos Ulberg made the best of a bad situation.
The trio from Auckland's City Kickboxing gym found themselves stuck in the United States after traveling over in early November for Ulberg's chance to earn a UFC contract.
Unable to return home until mid-December, the three Kiwi UFC stars based themselves in San Diego, linking up with world-renowned Brazilian Jiu-Jitsu gym Atos, with whom City Kickboxing is affiliated, at their headquarters.
For the past month, the three striking-dominant mixed martial artists have been training in nothing by BJJ, training at least twice daily. Ulberg explained it had been a great learning experience, and estimated he had been submitted between 200-300 times over the past month, but was noticing his improvement every day.
Getting in so many reps with high level grapplers, the Kiwis made huge improvements to their own game - large enough for Atos head coach André Galvão to promote Adesanya and Riddell from blue to purple belt - two steps below a black belt - while Ulberg received stripes on his white belt.
