The International Ski Federation (FIS) is reviewing its qualification process for cross-country skiing for the 2022 Games in Beijing due to concerns over "results inconsistencies" of several athletes competing this year.
And Tongan star Pita Taufatofua, who turned heads at the 2016 Summer Games in Rio with his shirtless, oiled-up look as the flag bearer for his country, has been linked to the controversy.
Taufatofua's rivals claim he didn't belong at the Winter Olympics. He was the first athlete from Tonga to represent his nation in both the summer and winter games. Taufatofua competed in the winter Olympics as a cross-country skier, despite living in a tropical nation that has no snow. He competed in taekwondo in Rio.
But Taufatofua's rivals revealed to Stuff he "cheated" his way into this year's Winter Olympics.
Cesar Baena, a member of the Venezuelan nordic ski team, believes Taufatofua cheated the system.
