Aaron Simpson will replace Wilson Gouveia and face Ed Herman at UFC 102 on August 29.
Sources close to the event have told MMADieHards.com. UFC.com has confirmed the report as well by updating their UFC 102 fight card.
Simpson was scheduled to face Dan Miller at UFN 19 in September, but an injury to Gouveia left Herman without an opponent.
Simpson is 5-0 in his mixed martial arts career, with all five of his fights ending by KO or TKO. Only one of his fights made it past the first round.
Herman (15-7) will be looking to build off his unanimous decision victory over David Loiseau at UFC 97. Before that victory, Herman had lost two straight.
