ONE Championship has officially confirmed the entire lineup for “ONE 161: Petchmorakot vs. Tawanchai,” with a world title fight and a kickboxing world grand prix headlining the action.

Four different sports are featured on the 12-bout card, which will air live from the Singapore Indoor Stadium on Thursday, September 29.

In the main event, ONE featherweight muay Thai world champion Petchmorakot Petchyindee defends his belt against fellow Thai superstar Tawanchai PK.Saenchai.

The Petchyindee man has looked unstoppable since he claimed the gold in 2020, adding three successful defenses to his resume over Yodsanklai Fairtex, Magnus Andersson and Jimmy Vienot. 

However, Tawanchai has quickly established himself as the top contender with three knockouts in three promotional victories, including a highlight-reel finish of No. 1-ranked bantamweight Saemapetch Fairtex.

This is a matchup that fans have clamored for since the PK.Saenchai Muaythaigym representative first signed with ONE, and he’s expected to be Petchmorakot’s most difficult challenger yet.

In the co-main events, the ONE heavyweight kickboxing world grand prix semifinals will pit four of the planet’s scariest strikers against each other.

Reigning ONE light heavyweight kickboxing world champion Roman Kryklia moves up a division to go after the tournament’s silver belt, and surging Brazilian Guto Inocente is the man standing in his way.

The Ukrainian has amassed a perfect 3-0 slate in ONE – and is riding an 11-fight winning streak overall – but he’ll get tested by the hard-hitting Inocente, who is 2-0 with back-to-back stoppages wins inside the ONE circle. 

Iraj Azazpour is also 2-0 since signing with ONE, and the Iranian slugger will face promotional newcomer Bruno Chavez in the other semifinal clash. 

Three more crucial bouts round off the main card, with massive implications for their respective divisions.

Zhang Lipeng (33-11-2) and No. 5 contender Saygid Izagakhmaev (20-2) will square off in a lightweight MMA clash, and with no obvious next challenger for Christian Lee‘s gold, either man could elbow their way into contention with a statement victory.

Two-time ONE women’s strawweight world title challenger Tiffany Teo (10-2) drops down a division with hopes of making another run toward the top, and she’ll be met by ONE women’s atomweight world grand prix runner-up Ritu Phogat (7-2).

Opening the main card, recent ONE flyweight world title challenger and current No. 3 contender Yuya Wakamatsu (15-5) aims to get back on track against Wang Shuo (15-6) after coming up short against former divisional king Adriano Moraes.

The lead card is topped by a high-profile muay Thai clash between former ONE bantamweight kickboxing world champions and past rivals Alaverdi Ramazanov and Capitan Petchyindee. 

Capitan dethroned the Russian with a KO last year, but No. 4-ranked Ramazanov now gets his chance for redemption in muay Thai, which is the more familiar rule set for both men. 

Also on the lead card, Sangmanee PK.Saenchai meets Zhang Chenglong and Ferrari Fairtex takes on Han Zi Hao in bantamweight Muay Thai bouts.

In MMA, “Reug Reug” Oumar Kane (3-1) faces Batradz Gazzaev (3-0) and Matheus Felipe (0-0) goes up against Ali Foladi (2-0) at heavyweight and middleweight, respectively, while Rodrigo Marello and Ruslan Bagdasarian battle in a bantamweight submission grappling match.
