UFC 177 will be headlined by two title fights.
Demetrious Johnson, the first-ever UFC flyweight champion, is set to put his 125-pound title on the line against Chris Cariaso in the co-main event of the pay-per-view card in Sacramento, California, on August 30. Yahoo! Sports first reported the bout.
UFC 177 will be headlined by an immediate rematch between T.J. Dillashaw and Renan Barao for the bantamweight championship.
Johnson (20-2-1) quickly returns to the Octagon less than three months following a unanimous decision victory over Ali Bagautinov at UFC 174. "Mighty Mouse" looks to defend his title for the fifth time after successful defenses against John Dodson, John Moraga, Joseph Benavidez and Bagautinov.
Cariaso (17-5), currently ranked at No. 8 in the UFC flyweight rankings, was scheduled to face Kyoji Horiguchi at the UFC Fight Night 52 card in Japan, but instead gets a championship fight with Johnson. He enters the title fight riding a three-fight win streak with victories over Iliarde Santos, Danny Martinez and Louis Smolka.
