Joe Pyfer will lock horns with Kelvin Gastelum in a middleweight bout at UFC on ESPN 64.

Pyfer recently confirmed the pairing on Instagram following an initial report from MMA Mania. UFC on ESPN 64 is expected to take place at Arena CDMX in Mexico City on March 29, though the venu has not been officially confirmed by the Las Vegas-based promotion.

Pyfer has been victorious in six of his last seven professional outings. After earning a UFC contract on Dana White's Contender Series in 2022, "Bodybagz" finished his first three Octagon foes before fallling to Jack Hermansson in the UFC Fight Night 236 main event this past February. The 28-year-old Pennsylvania native rebounded in his most recent appearance, when he knocked out Marc-Andre Barriault in the opening stanza of their encounter at UFC 303.

Gastelum will be making his 24th Octagon appearance against Pyfer. "The Ultimate Fighter 17" winner has been triumphant in two of his last three in UFC competition -- including a three-round verdict over in his lone outing of 2024. Gastelum's resume includes victories over the likes of Ronaldo Souza, Michael Bisping, Johny Hendricks, Nate Marquardt and Jake Ellenberger, among others.
