World number one Aryna Sabalenka will face Nick Kyrgios in a 'Battle of the Sexes' exhibition match in the United Arab Emirates later this year.
Belarus' Sabalenka, 27, and 30-year-old Australian Kyrgios - ranked 652nd in the world - are set to play each other at the Coca-Cola Arena in Dubai on 28 December.
Four-time Grand Slam winner Sabalenka is the reigning Wimbledon and US Open champion.
Kyrgios, who reached a career-high 13th in 2016, has only played five matches this year since returning from a serious wrist injury that kept him out for 18 months.
