Mario Piazzon and Guilherme Uriel face off ahead of DWCS heavyweight bout

Brazilian heavyweight Mario Piazzon is set to face Guilherme Uriel at the Meta Apex in Las Vegas on August 25, 2026, as part of Dana White’s Contender Series. The matchup has intensified following a tense face-off at the official weigh-ins, where the two fighters touched foreheads.

Piazzon indicated that the tension stems from personal friction, noting that Uriel had blocked him and his associates on Instagram. Piazzon expressed a preference for the ‘hostile atmosphere,’ drawing parallels to his 2023 Contender Series appearance where he won via disqualification against Alexander Soldatkin but failed to secure a UFC contract.

Both fighters are competing for a potential UFC deal. Piazzon is looking to rebuild following a loss to Alex Junius, while Uriel seeks to move past a previous Contender Series loss to Josh Hokit.
