Former UFC heavyweight champion Fabricio Werdum has been suspended until 2020 after failing an out-of-competition drug test earlier this year.

Werdum (23-8-1) tested positive for the anabolic steroid trenbolone and its metabolite epitrenbolone ahead of a proposed main event bout with Oleksiy Oliynyk at UFC: Moscow.

The 41-year-olds two-year ban will start retroactively from May 22nd which was the date of his original provisional suspension.

The Brazilian heavyweight is widely regarded as one of the best heavyweights in MMA history with his career culminating with a submission win over Cain Velasquez in 2015 to win the UFC heavyweight title.

‘Vai Cavalo’ also brought an end to Fedor Emelianenko’s unbeaten streak in 2010 and holds notable wins over the likes of Alistair Overeem, Mark Hunt and Antonio Rodrigo Nogueira.

Werdum last fought in the main event of UFC: London in March of this year where he suffered a fourth-round KO loss to Alexander Volkov.
