Thai megastar Stamp Fairtex learned the hard way to listen to her body.ONE Championship’s only three-sport world champion spent more than two years away from competition after facing a setback in her recovery from a serious knee injury.According to Stamp, it was her over-eagerness to get back to 100 percent that further delayed her return.The former ONE atomweight MMA world champion had to relinquish her 26 pounds of gold earlier this year after failing to defend it against now undisputed champ Denice Zamboanga.What followed was a grueling rehabilitation process that tested her mental fortitude.Rushing her recovery backfired big time and taught her a painful lesson.The Fairtex Training Center affiliate told ONE Championship in an exclusive interview:"This is my comeback fight after more than two years. The past two years were difficult. It changed my routine from training Muay Thai every day to doing physical therapy every day. There was a time when I felt like I was pushing too hard."
