Karl Williams (10-1) will take on undefeated Brazilian Jhonata Diniz (7-0) in his fourth Octagon assignment. The news was first reported by Laerte Viana in a post to X (formerly known as Twitter).
The news was later confirmed by both competitors on their social media accounts.
Williams will lock horns with Diniz aiming to extend his three-fight winning streak, which includes unanimous decision victories over Lukasz Brzeski, Chase Sherman and most recently Justin Tafa.
Meanwhile, Diniz will make his sophomore appearance inside the Octagon coming off a spectacular Round 2 knockout over Austen Lane in his promotional debut at UFC on ESPN 55 on April 27.
