HBO’s boxing broadcast July 21 from Las Vegas will be a tripleheader after all.

BoxingScene.com has learned that a middleweight match that’ll pit undefeated Demetrius Andrade against Yamaguchi Falcao will be added to the two fights HBO announced Friday. An agreement is in place for the Andrade-Falcao fight and an announcement is imminent.

Andrade-Falcao has been in the works for several weeks. When it wasn’t revealed as part of the telecast Friday, however, it prompted speculation that the fight wouldn’t take place.

The 30-year-old Andrade (25-0, 16 KOs), a 2008 Olympian from Providence, Rhode Island, soundly defeated Alantez Fox (23-1-1, 11 KOs) in his last fight, a 12-rounder October 21. HBO televised the Andrade-Fox fight from Turning Stone Resort Casino.

The 30-year-old Falcao (15-0, 7 KOs, 1 NC), a 2012 Olympian from Sao Paulo, Brazil, most recently beat Colombia’s Richard Gutierrez (30-18-2, 19 KOs, 1 NC) by unanimous decision in an eight-rounder March 31 in Quincy, Massachusetts. Andrade, a highly skilled southpaw and two-time super welterweight champion, will be by far the toughest opponent of Falcao’s four-year pro career.

The main event of HBO’s three-bout broadcast July 21 will be a 12-rounder between newly crowned WBO super welterweight champ Jaime Munguia (29-0, 25 KOs) and mandatory challenger Liam Smith (26-1-1, 14 KOs).

Mexico’s Munguia, 21, replaced England’s Smith, 29, on short notice and knocked out Sadam Ali (26-2, 14 KOs) in the fourth round to win the WBO 154-pound title May 12 at Turning Stone. Smith withdrew from his fight against Ali due to a skin condition that prevented him from training.

This HBO tripleheader also will include a 12-round, 130-pound title bout that’ll match Puerto Rico’s Alberto Machado (19-0, 16 KOs) against Ghana’s Rafael Mensah (31-0, 23 KOs). Mensah, 27, is the No. 1 contender for the 27-year-old Machado’s WBA super featherweight title.

The three aforementioned fights will be part of a card at Hard Rock Hotel & Casino.
