The FA Cup draw has thrown up some enticing last 32-round clashes with SCG Muang Thong United taking on BG Pathum United and Buriram United facing Police Tero.
The matches will be played on Dec 5-6.
Yesterday's draw was presided over by Football Association of Thailand secretary-general Patit Supaphong and attended by Thai Beverage Co Ltd executive director Surapol Utintu.
A total of 15 teams from Thai League 1 have made the last 32 stage of the tournament with five other teams being from Thai League 2, 10 from Thai League 3 and two from the Thailand Amateur League.
One of the most intriguing battles will be between former top-flight winners Muang Thong and visiting Thai League 1 pacesetters Pathum United.
Buriram will host Police Tero and reigning Thai League 1 champions Chiang Rai United will seek to avenge their league loss to Sukhothai at their home ground. Defending FA Cup champions Port will face Thai League 2 side MOF Customs United.
The tournament winners will earn five million baht plus a chance to participate in the 2022 AFC Champions League group stage.
