The 28-year-old Calgary native, who piloted Canada to gold at the Sochi Games in two-man bobsled, tweeted Tuesday that she would be at "The Ultimate Fighter Nations Finale" card on April 16 in Quebec City.
"Looking forward to entering the octagon on April 13th in Quebec City!" said Humphries from her verified Twitter account. "Venez nous voir!"
Humphries added a "tale of the tape" picture with her height and weight.
A UFC spokesman said Humphries is a fan of mixed martial arts who is "getting her first taste of fun training." But she is not fighting.
The bobsledder will attend a public event April 13 and will "learn a few things firsthand with some of our fighters.
"She'll then come to the fight and will likely also attend the weigh-ins," the UFC spokesman said. "She's been a huge fan so we're happy to have her out.
Humphries, along with teammate Heather Moyse, were Canada's flagbearers at the Winter Olympics closing ceremony on Feb. 23.
The Quebec card will serve as the finale of the UFC reality TV show that has put a team of Canadian fighters against a group of mixed martial artists from Australia.Suggest a correction
