The 29-year-old former Olympic judo bronze medallist is due for a return fight against Amanda Nunes in December
Ultimate Fighting Championship president Dana White said Wednesday the bout would headline the UFC 207 card in Las Vegas.
The 29-year-old Rousey, a former Olympic judo bronze medallist, held the UFC 135-pound crown for three years, from November of 2012 to November of 2015 -- when she was brutally knocked out by Holly Holm in Melbourne in one of the biggest shocks in the history of UFC.
Holm lost the title in her first attempted defence against Meisha Tate.
Brazil's Nunes won the title with a first-round submission victory over Tate in July.
