Another heavyweight fight is close to being added to UFC 213.

The UFC is working on booking Travis Browne vs. Aleksei Oleinik for the July 8 card, according to multiple sources.

Browne (18-6-1) has lost his last three fights in a row, most recently getting knocked out by Derrick Lewis in February. Prior to that loss, he was defeated by Fabricio Werdum and Cain Velasquez. “Hapa” hasn’t won a fight since January 2016.

Meanwhile, Oleinik (51-10-1) has won 12 of his last 13 fights. The Russian veteran is coming off an impressive Ezekiel choke victory over Viktor Pesta in January, which marked the first time in UFC history someone won a fight via that particular choke.

Also already slated for the card, which is set for the T-Mobile Arena in Las Vegas, is a heavyweight trilogy fight between Alistair Overeem and Werdum.

The promotion has yet to announce a main event.
