A featherweight bout is the latest edition to the UFC 179 fight card as Darren Elkins will meet Lucas Martins in a bout that is expected to take place on the preliminary card. 
The fight booking was announced by the UFC on late Monday evening.
UFC 179 will come from the Maracanazinho Gymnasium in Rio de Janeiro, Brazil on October 25th and will be headlined by Jose Aldo defending the UFC featherweight title against Chad Mendes.
Elkins (17-4) has dropped two of his last three fights after winning five straight fights once he dropped down to the featherweight division. In his most recent fight, he lost a decision to Jeremy Stephens at UFC on FOX 10 and his last victory came in August of last year against Hatsu Hioki.
Martins (15-1) came to the UFC as a lightweight and made his UFC featherweight debut in July as he defeated Alex White by knockout in the third round. He won a performance of the night in that victory and he has won a fight night bonus in two of his last three fights.
