HBO Boxing kicks off the fall with an all-action showdown featuring one of the most exciting fighters in the sport when HBO BOXING AFTER DARK: LUCAS MATTHYSSE VS. VIKTOR POSTOL AND HUMBERTO SOTO VS. ANTONIO OROZCO is seen SATURDAY, OCT. 3 at 10:15 p.m. (live ET/tape-delayed PT) from StubHub Center in Carson, Cal., exclusively on HBO. The HBO Sports team will be ringside for all the action, which will be available in HDTV, closed-captioned for the hearing-impaired and presented in Spanish on HBO Latino.

The doubleheader will also be available on the HBO NOW and HBO GO platforms.

In the headline event, Lucas Matthysse (37-3, 34 KOs) of Trelew, Chubut, Argentina and Viktor Postol (27-0, 11 KOs) of Kiev, Ukraine, compete for a vacant 140-pound title belt in a 12-round super lightweight fight.

Matthysse, celebrating his 33rd birthday this week, fought the rugged and relentless Ruslan Provodnikov last April, scoring a thrilling triumph in a contest many ringside observers view as the leading candidate for fight of the year honors. The undefeated Postol is a skilled 31-year-old who is embracing the challenge of meeting one of the sport’s most devastating punchers at a venue known for eye-opening outcomes.

Opening the evening is a ten-round super lightweight bout featuring Humberto Soto (65-8-2, 35 KOs) and Antonio Orozco (22-0, 15 KOs).  Soto, 35, of Los Mochis, Sinaloa, Mexico, is a skilled veteran with three division world titles on his resume and more than three times the professional experience of his opponent. Orozco, a 27-year-old Mexican native who currently hails from San Diego, is seeking national recognition in a highly competitive division.

The Oct. 3 doubleheader kicks off an impressive fall lineup on multiple HBO Boxing platforms. HBO Pay-Per-View® will present blockbuster middleweight bouts featuring Gennady Golovkin vs. David Lemieux (Oct. 17) and Miguel Cotto vs. Canelo Alvarez (Nov. 21), while a “World Championship Boxing®” card will showcase the 2014 BWAA “Fighter of the Year” Terence Crawford in prime time on Oct. 24 vs. Dierry Jean. Welterweights stars Timothy Bradley Jr. and Brandon Rios collide in an intriguing 147-pound showdown two weeks later in Las Vegas (Nov. 7).

Immediately following the live doubleheader from Carson, HBO will premiere “Road To Golovkin/Lemieux,” a special previewing the upcoming middleweight unification bout between Gennady Golovkin and David Lemieux that will air live on HBO Pay-Per-View®.
