The Canadian triumphed in the women's 75-kilogram freestyle wrestling contest at Rio 2016 and is planning to defend her title at Tokyo 2020, postponed until July 23 to August 8 next year as a result of the COVID-19 pandemic. 

Wiebe has not competed since March, however, when she earned her Olympic place at the Pan-American qualifying event in Ottawa.

Wrestling events have been suspended until this month due to the global health crisis. 

The 31-year-old Wiebe will return to the mat at the Individual World Cup in the Serbian capital from December 12 to 18. 

"This competition will be a huge step in my Olympic preparations by providing an opportunity to gain experience competing in these new, uncertain circumstances," said Wiebe. 

"I’m hungry to compete and build towards my Tokyo performance goals."

Fellow Canadian Amar Dhesi is also set to compete at the World Cup, having qualified for his first Olympic Games in the men's 125kg division.

The World Cup event is being held in place of the UWW World Championships.

UWW had set a benchmark requiring that at least eight of the 10 top nations from the 2019 World Championships and 70 per cent of total athletes attend the 2020 edition, but this criteria was not met due to the pandemic. 

"We want to see our athletes compete again on the mat," said UWW President Nenad Lalović.

"It’s important to our organization and we are committed to providing them an opportunity.

"There are real challenges to overcome, but we are working together to find a safe and acceptable format where our top athletes can compete in a world class event."
