Featherweights Charles Oliveira (16-4 MMA, 4-4 UFC) and Estevan Payan (14-4 MMA, 0-1 UFC) are the latest additions to this fall’s UFC 166 lineup. The Houston Chronicle first reported the matchup, which UFC officials later confirmed. The fight is expected for the event’s preliminary-card, though it’s not clear whether it will serve on the FOX Sports 1-televised or Facebook-streamed portion. UFC 166 takes place Oct. 19 at Houston’s Toyota Center and is headlined by a rubber match between heavyweight champ Cain Velasquez and ex-champ Junior dos Santos . Despite a good showing in his most recent outing, Oliveira is badly in need of a win in the UFC. The Texas-based Brazilian took on ex-champ Frankie Edgar at UFC 162 and lost a unanimous decision. Previously, he was knocked out by Cub Swanson at UFC 152
