Former Ultimate Fighting Championship (UFC) Lightweight title challenger Renato Moicano returns to action this weekend (Sat., April 4, 2026), taking on surging Scottish standout Chris Duncan in the main event of UFC Vegas 115 inside the Meta Apex in Las Vegas, Nevada.
What makes this matchup unique? Both fighters share the same home gym.
Moicano and Duncan train out of the legendary American Top Team — one of the biggest and most talent-rich camps in all of MMA — which naturally created an unusual dynamic heading into fight week.
While teammate vs. teammate matchups can sometimes lead to fighters switching camps or avoiding one another entirely, that wasn’t the case here.
Instead, things got… complicated.
“The gym — I’m not going to say was divided, but some guys that helped him were not training with me and some guys that helped me weren’t helping him,” Moicano told Full Send MMA . “At the end of the day, we’re fighting each other. How can you train with both guys? But at the same time, some guys were training with both Chris and me. So, it was kind of confusing. This is a sport. I don’t hate him. I have nothing against him — it’s just a sport.”
It’s a delicate balance, but not unheard of at a gym as massive as ATT, where multiple elite fighters often prepare for overlapping fights.
Duncan is no stranger to that dynamic, either.
The Scottish lightweight previously fought a teammate in UFC Vegas 108, going to war with Mateusz Rebecki in a Fight of the Night clash that quickly became a Fight of the Year contender.
For context, Moicano has been part of ATT since around 2017, while Duncan joined the gym after earning his UFC contract on Contender Series in late 2022.
Despite the shared training room — and the occasional awkwardness that comes with it — both men are promising fireworks.
