Carlos Adames and Patrick Teixeira were supposed to meet Saturday night in an elimination match to determine the mandatory challenger for the WBO’s junior middleweight title.

Now that WBO 154-pound champion Jaime Munguia officially has moved up to middleweight, the WBO has sanctioned Adames-Teixeira as a fight for an interim portion of that championship in Las Vegas.

Carl Moretti, vice president of boxing operations for Bob Arum’s Top Rank Inc., confirmed to BoxingScene.com on Wednesday that Adames-Teixeira now is an interim 154-pound championship match. ESPN.com first reported that the WBO made Adames-Teixeira a title fight.

Moretti also said that because Munguia is in the process of vacating his title that the Adames-Teixeira winner likely will be elevated from interim champion to world champion next week at the WBO’s annual convention in Tokyo.

The Dominican Republic’s Adames (18-0, 14 KOs) is ranked No. 1 among the WBO’s junior middleweight contenders. Brazil’s Teixeira (30-1, 22 KOs) is ranked No. 2 by the WBO.

Mexico’s Munguia (34-0, 27 KOs) will make his debut as a full-fledged middleweight January 11 in San Antonio. Munguia is set to box Ireland’s Gary O’Sullivan (30-3, 21 KOs) in a 12-rounder that night at The Alamodome.

Adames-Teixeira will be streamed Saturday by ESPN+ as part of a card from The Chelsea inside The Cosmopolitan.

That show, which will start at 6:30 p.m. ET/3:30 p.m. PT, will be headlined by former WBO featherweight champion Oscar Valdez. Mexico’s Valdez (26-0, 20 KOs) is scheduled to meet Mexican veteran Andres Gutierrez (38-2-1, 25 KOs) in a 10-round, 130-pound bout.

Former featherweight and junior featherweight champ Carl Frampton also is slated to fight on this show Saturday night. Northern Ireland’s Frampton (26-2, 15 KOs) and Tyler McCreary (16-0-1, 7 KOs), of Toledo, Ohio, are set to square off in a 10-rounder before the Valdez-Gutierrez bout.

Frampton will fight for the first time since IBF featherweight champ Josh Warrington (30-0, 7 KOs) defeated him by unanimous decision 11 months ago in Manchester, England.
