SINGAPORE - Former Ultimate Fighting Championship (UFC) bantamweight champion Holly Holm, known popularly as the woman who knocked out Ronda Rousey, could headline UFC's event here on June 17 at the Singapore Indoor Stadium.

Hours before a UFC promotional event on Wednesday morning (April 12) to kick-off ticket sales, popular mixed martial arts websites MMAmania.com and MMA Fighting wrote that Holm, whose win over Rousey ranked as one of the sport's biggest upsets, will enter the cage in a bantamweight duel against Bethe Correia.

Rumours that Holm could anchor the June show here first appeared in March. After dethroning Rousey, Holm lost the bantamweight belt to Miesha Tate in her first title defence.

A UFC spokesman told The Straits Times that nothing is official yet and more details about the fight's main and co-main events will be revealed at a later date.

Confirmed bouts on the fight card include a welterweight clash between former lightweight champion Rafael dos Anjos and Tarec Saffiedine, while Andrei Arlovski will take on Marcin Tybura in the heavyweight division.

This is the UFC's second event here, after its inaugural show in 2014, held at Marina Bay Sands.

Tickets for the event are on sale and are priced at $378, $248, $128, $98 and $58 (excluding service charges and fees). Tickets are available at www.sportshubtix.sg.
