McCall, Moraga added to L.A. card
UFC officials announced the bout earlier on Thursday.
McCall last fought at the promotion's June "UFC on FX" card, dropping a unanimous decision to Demetrious Johnson. The two had met earlier this year in an opening round bout of the four-man flyweight tournament, but it ended in a draw.
Meanwhile, Moraga is on a four-fight winning streak, but has yet to compete in the UFC. His last loss came against John Dodson back in 2010 under the Nemesis Fighting banner.
