The UFC finally has its first mongoose on the roster.

The oft-rumored signing of flyweight Darrell Montague (13-2 MMA, 0-0 UFC) has come to fruition, and the Californian will meet former title challenger John Dodson (14-6 MMA, 3-1 UFC) in October at UFC 166.

UFC officials on Saturday announced the signing of “The Mongoose” and the fall matchup.

UFC 166 takes place Oct. 19 at Toyota Center in Houston. The main card, featuring a heavyweight title fight between champion Cain Velasquez and former champ Junior dos Santos, airs on pay-per-view following prelims on FOX Sports 1 and Facebook. The addition of Dodson-Montague brings the card to 13 fights.

The 25-year-old Montague, whose Millennia MMA training partners include the UFC’s Lorenz Larkin and Bellator vets Saad Awad and Georgi Karakhanyan, in on a four-fight win streak that includes three stoppages.

In 2011, Montague improved to 9-1 when he beat Ulysses Gomez at Tachi Palace Fights 8 to win that promotion’s flyweight title. But he lost it in his first defense to current UFC flyweight Ian McCall before going on his current run. Of the 13 wins on his resume, 10 have come by stoppage with an equal amount of knockouts and submissions.

Dodson will be fighting for the first time since a flyweight title fight loss to champion Demetrious Johnson in January. He lost that fight by unanimous decision, but picked up a “Fight of the Night” bonus for his efforts. Before that, he got the title shot by virtue of a five-fight win streak , including three straight to start his UFC career over T.J. Dillashaw, Tim Elliott and Jussier Formiga.

With the addition, the latest UFC 166 card includes:
