Despite the defeat, Kassman felt honoured to take the ring against a world number 1 and she is proud to have donned the PNG colours at the biggest sporting event.
Kassman went down to her British number 3 ranked and 2015 Taekwondo World Champion opponent, Bianca Walkden, 14-1 in the +67kg category fight.
Kassman said: “Going into the fight, I knew it was going to be challenging and a hard task but I wasn't nervous nor intimidated.
“I stuck to it and fought all three bouts and I wouldn't have wanted the draw any other way,” Kassman told Loop PNG.
