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.

In his first appearances at featherweight, Oliveira went 2-0 with wins over Eric Wisely and Jonathan Brooks. As a lightweight, he went 2-2 in the octagon.

Payan, meanwhile, looks to get on the right foot after a decision loss to Jeremy Stephen in his UFC debut at UFC 160. The Arizona-based fighter transitioned to the promotion after winning back-to-back fights in the now-defunct Strikeforce.

Prior to his setback, Payan had won five straight bouts.

With the addition to the lineup, UFC 166 now includes:

Champ Cain Velasquez vs. Junior dos Santos – for heavyweight title Daniel Cormier vs. Roy Nelson Gilbert Melendez vs. Diego Sanchez Gabriel Gonzaga vs. Shawn Jordan Tim Boetsch vs. Luke Rockhold Hector Lombard vs. Nate Marquardt K.J. Noons vs. George Sotiropoulos Tony Ferguson vs. Mike Rio Adlan Amagov vs. T.J. Waldburger George Roop vs. Francisco Rivera Matt Grice vs. Jeremy Larsen Charles Oliveira vs. Estevan Payan
