The UFC ’s champions are getting busy. With nearly every champion in the promotion already lined up for a fight or just coming off of a defense, that left UFC flyweight champion Demetrious Johnson as the only titleholder sitting idly by, waiting for his next defense. Johnson is no longer waiting, as UFC president Dana White announced via UFC Tonight on Wednesday that Demetrious Johnson would put his belt on the line in a rematch against Joseph Benavidez at The Ultimate Fighter 18 Finale . Johnson (18-2-1) is fresh off of his UFC on Fox 8 main event victory over John Moraga in September in July.
