ONE Championship’s first event on Amazon Prime has taken a hit to the lineup.

Rodtang Jitmuangnon has pulled out of his muay Thai flyweight grand prix semifinal bout due to illness. His bout against Savvas Michael has been scratched from the event which takes place at Singapore Indoor Stadium on Friday.

MMA Junkie confirmed the news with a ONE Championship official following an initial report from MMA Fighting.

ONE on Prime Video 1 will proceed with 9 total fights, consisting of four muay Thai bouts and five MMA fights. In the main event, Adriano Moraes faces Demetrious Johnson in a rematch for the ONE Championship flyweight title.

Rodtang faced Johnson earlier this year in a mixed rules bout that alternated rulesets between muay Thai and MMA each round. Johnson defeated Rodtang by submission in the second round.

In May, Rodtang returned to muay Thai competition as a part of the flyweight grand prix, defeating Jacob Smith by unanimous decision to advance to the semifinals against Michael. Unfortunately, that fight will not take place following Thursday’s weigh-ins when Rodtang failed to submit a sample for the mandatory hydration test.

With the removal, the ONE on Prime Video 1 lineup is as follows:

• Adriano Moraes vs. Demetrious Johnson – for ONE Championship flyweight title
• Nong-O Gaiyanghadao vs. Liam Harrison – for ONE Championship bantamweight title (Muay Thai)
• Marcus Almeida vs. Kirill Grishenko
• Amir Aliakbari vs. Mauro Cerilli
• Superlek Kiatmoo9 vs. Walter Goncalves (Muay Thai)
• Amir Naseri vs. Jonathan Haggerty (Muay Thai)
• Diandra Martin vs. Amber Kitchen (Muay Thai)
• Itsuki Hirata vs. Hequin Lin
• Zebaztian Kadestam vs. Iuri Lapicus
