Report: Ex-champ Werdum to return vs. Oleinik at UFC 250

Former UFC heavyweight champion Fabricio Werdum will return to the Octagon against Aleksei Oleinik at UFC 250 on May 9 in Sao Paulo, Brazil, sources told Combate's Evelyn Rodrigues and Raphael Marinho, according to Sherdog.com's Jay Pettry via Google Translate.

Contracts have reportedly not yet been signed, but Werdum and Oleinik have verbally agreed to the fight, according to Rodrigues and Marinho.

Werdum hasn't competed since a March 2018 loss to Alexander Volkov. He tested positive in a USADA drug test that April, which resulted in the cancellation of his scheduled bout against Oleinik for later that year. "Vai Cavalo" received a two-year suspension for the failed test and is eligible to return April 1, 2020.

The 42-year-old Werdum is 3-3 since he submitted Cain Velasquez to win the UFC heavyweight belt in 2015.

Oleinik snapped a two-fight skid with a submission of Maurice Greene in January. Before that, "The Boa Constrictor" suffered first-round knockout defeats to Walt Harris and Alistair Overeem. Oleinik has fought in 72 pro bouts, 11 of which have come under the UFC banner.
