Gymmates No More: Renato Moicano and Chris Duncan Put ATT Ties Aside for UFC Main Event

Renato Moicano and Chris Duncan, long-time teammates at American Top Team (ATT), are set to face each other as opponents in a lightweight main event. This highly anticipated bout, UFC Vegas 115, will take place on April 4, 2026, at the Meta APEX facility in Las Vegas, Nevada. Moicano will be defending his ranking against Duncan, a surging gym mate aiming for his first significant victory.

Renato Moicano vs. Chris Duncan: The Matchup

This main event, UFC Fight Night: Moicano vs. Duncan, is hosted at the Meta APEX in Las Vegas. Moicano, a seasoned ATT veteran and contender, joined the gym in 2017 and moved to the lightweight division in 2020. His impressive record includes victories over notable fighters such as Jalin Turner, Benoit Saint Denis, Calvin Kattar, and Cub Swanson. Duncan, a Scottish lightweight with a 15-2 professional record, also trains at ATT. He enters this fight following a submission victory against Terrance McKinney in December 2025.

Moicano is looking to rebound after a challenging 2025, which saw him suffer consecutive losses: a first-round submission to Islam Makhachev in January and a decision loss to Beneil Dariush in June. Conversely, Duncan has regained momentum since his 2024 submission defeat to Manuel Torres, securing impressive wins, including a first-round guillotine choke against Bolaji Oki in 2024 and his recent submission of McKinney.

The American Top Team Dilemma

During fight week, both athletes commented on the unusual situation of facing a gym mate, each offering their perspective. Duncan emphasized that their shared bond from American Top Team (ATT) remains, even as they compete to advance their careers.

“He was in the same gym and we were in the sauna together … a lot of people don’t get what I’m doing, and me and Mo do. We have so much respect for each other that it’s just going to be fighting … Whoever wins, wins, and people can’t fathom that … people are not bred like me, where I’m on a different level.”

Moicano revealed American Top Team's internal policy, stating that owner Dan Lambert and the coaching staff generally prefer to prevent teammates from competing against each other. However, he acknowledged that with numerous elite fighters training together, such matchups are sometimes unavoidable. He cited flyweights Kyoji Horiguchi and Alexandre Pantoja as an example of teammates who might eventually face each other in a high-stakes bout.

“The gym always tries to avoid this situation. Dan Lambert and all the coaches want to avoid it as much as possible because it’s not good, people from the same gym fighting, that’s not the best scenario. But sometimes you have to do that because you don’t have any option, and I’m talking in a career mode. I’ve been one year out and they gave me this opportunity for the main event, and at the same time Chris Duncan wants to be in the rankings, so it was beneficial for everybody but not for the gym.

“I tell the fighters, you don’t want to fight another guy from your gym, but that could happen, we never know. At ATT you have guys like Kyoji Horiguchi and Pantoja, and they’re the best at 125 and eventually they’re going to fight each other. Sometimes you have to fight your teammates and it’s tough.”

“It was a little bit different training under the same roof as Chris because I never thought I would fight somebody from American Top Team, but it happens and I just have to be cordial. I respect him, I have nothing against him, I just want to win. I want to win that fight and I have no bad blood at all.”

Duncan, for his part, highlighted the straightforward nature of this specific matchup: two teammates from the same gym, training in separate camps, with a mutual understanding that the fight's outcome will dictate their respective positions in the lightweight rankings. Both fighters assert that their friendship will endure beyond the bout in Las Vegas, but acknowledge that the competition itself takes precedence.
