UBERLANDIA, Brazil – After a grappling-heavy and at times sloppy affair,  Diego Rivas (6-0 MMA, 1-0 UFC) emerged with the unanimous decision victory (30-27, 30-27, 30-27) over  Rodolfo Rubio (12-7 MMA, 0-1 UFC). The featherweight bout closed out the preliminary card of today’s UFC Fight Night 56 event at Ginasio Municipal Tancredo Neves in Uberlandia, Minas Gerais, Brazil.
