MMAFighting.com confirmed the news after Combat Press initially published the report.
For Case (22-4), the bout marks his fifth UFC appearance. The 26-year-old fighter is 4-0 inside the UFC Octagon to this point, notching a submission of Kazuki Tokudome, a TKO of Frankie Perez, and two decisions—one against Fransico Trevino and one against Yan Cabral.
The 21-year-old Matthews (9-1), meanwhile, is 3-1 in UFC action. He’s earned a finish in all three of his victories—a submission of Dashon Johnson, a submission of Vagner Rocha, and a TKO of Akbarh Arreola—while his sole defeat came at the squeeze of James Vick, who defeated Matthews via first-round guillotine.
The UFC Fight Night 84 card is headlined by a heavyweight title between Mark Hunt (11-10-1) and Frank Mir (18-10). A welterweight clash between Hector Lombard (34-4-1, two no-contests) and Neil Magny (17-4) will serve as the evening’s co-main event.
