Two Brazilian middleweights will return from long layoffs at UFC 197.

Vitor Miranda, who hasn’t fought since August of 2015, is set to face Marcelo Guimaraes, who last competed in June of 2014, multiple sources told MMAFighting.com. UFC 197 is scheduled for March 5 at Las Vegas’ MGM Grand Garden Arena.

Miranda (11-4), finalist of the third edition of TUF Brazil as a heavyweight, cut down to 185 pounds after the reality show and scored back-to-back knockouts over Jake Collier and Clint Hester.

Guimaraes (9-1-1), who also holds a 2-1 UFC record, made his debut as a middleweight in his last bout, defeating Andy Enz via decision. The former Jungle Fight champion went 1-1 at 170 pounds, but decided to move up to cut less weight.

UFC 197 will be headlined by a pair of championship fights. Rafael dos Anjos puts his lightweight title on the line against featherweight champion Conor McGregor, while Holly Holm looks to defend her 135-pound belt for the first time against Miesha Tate.
