Lumpinee Boxing Stadium is hosting a ONE Championship double header this week.
Before ONE Fight Night 11 takes centre stage on Saturday, ONE Lumpinee 20 goes down on Friday and will bring another stacked fight card.
The main event will see Petsukumvit Boi Bangna shoot for his fourth straight ONE Championship win when he takes on promotional newcomer Jaosuayai Sor Dechapan.
Petsukumvit has reeled off three wins in the space of three months since making his debut in February.
The current Rajadamnern Stadium Muay Thai world champion was last seen outpointing Kongtoranee Sor Sommai at ONE Lumpinee 6.
Jaosuayai has won his last two on the stadium circuit, and the 21-year-old is ready to unleash his flashy fighting style on the global stage in a huge main event.
In the co-feature, Yodkritsada Sor Sommai and Theptaksin Sor Sornsing will run it back.
The experienced pair faced off in an all-out war at ONE Lumpinee 10 in March.
After standing toe-to-toe for three full rounds, it was Theptaksin who took home a unanimous decision victory in their first encounter.
Both fighters, however, were rewarded for the epic battle with a performance bonus, courtesy of ONE chairman and CEO Chatri Sityodtong.
Headlining the international portion of the card is a bantamweight Muay Thai match-up between Thailand's Yod-IQ PK Saenchai and Uzbek veteran Mavlud Tupiev.
Yod-IQ made his ONE debut in March, when he scored a dramatic second-round knockout win over Belgium's Samuel Bielen.
The victory extended the 21-year-old's winning streak to four, and his overall record to 116-35-15.
The experienced Tupiev is fresh from the biggest win of his fighting career in March.
At ONE Lumpinee 8, the 32-year-old defeated former ONE bantamweight kickboxing world champion Alaverdi Ramazanov by decision.
In MMA action, featherweight newcomers Konstantin Marareskul and Bartosz Skrok will put their undefeated records on the line, while Russian flyweight Ivan Orekhov will make his debut against fellow countryman and former kickboxing standout Torepchi Dongak.
The first bout starts at 7.30pm at Lumpinee and Channel 7 will show live the programme from 8.30pm.
