[2] In 1989, after a run at Bantamweight and Super Bantamweight where he defeated Langsuan, Dokmaipa, Detduang, and Wangchannoi, Noppadet was pushed up to Featherweight and matched with a bigger and more experienced Jaroenthong Kiatbanchong, who gave him a big cut on the forehead and cruised to a decision victory.

[3] The loss proved to be tough on the 18-year-old Noppadet who fell into a long slump as he went 2-11-1 from July, 1989 to December, 1990.

[4] Soon after joining his new gym, Noppadet broke out of his slump and had a career resurgence culminating in him winning the Rajadamnern Stadium Featherweight title in his third fight against Wanwiset Kaennorasing.

[5] He was one of a few fighters to have a purse as high as ฿150,000 Thai baht, which he earned against Jaroenthong Kiatbanchong,[4] and despite retiring at an early age, he fought against many notable fighters such as Chamuekpet Hapalang, Somrak Kamsing, Wangchannoi Sor.Palangchai, Jaroenthong Kiatbanchong, Langsuan Panyuthaphum, Veeraphol Sahaprom,[6] Namkabuan Nongkeepahuyuth, Boonlai Sor.Thanikul,[7] Dokmaipa Por.Pongsawang, Rajasak Sor.Vorapin,[8] Wanwiset Kaennorasing, Kangwannoi Or.Sribualoi, Yodpetch Sor.Jitpattana, Kuekrit Sor.Nayaiam, Wanghin Por.Chaiwat, and Detduang Por.Pongsawang.
