Costa revealed the matchup via Instagram on Wednesday. The UFC has not formally announced the pairing. UFC 226 takes place on July 7 at the T-Mobile Arena in Las Vegas and is headlined by a heavyweight tilt between reigning champion Stipe Miocic and 205-pound king Daniel Cormier.
“Borrachinha” pulled out of the initially scheduled bout with Hall due to a torn biceps. The 26-year-old Brazilian is 11-0 thus far in his MMA career, including a trio of triumphs under the UFC banner. Most recently, he scored a second-round TKO of Johny Hendricks at UFC 217 in November.
Hall will return for the first time since a scary weight cut forced him to withdraw from a matchup with Vitor Belfort at UFC Fight Night 125 in January. Hall last competed at UFC Fight Night 116, where he halted a three-bout skid with a second-round TKO of Krzysztof Jotko.
