It's been a whirlwind week for former UFC champion Fabricio Werdum. Just a day after reportedly being booked for one of the biggest fights of his career, Vai Cavalo is instead now looking at a battle with the United States Anti-Doping Agency due to a flagged out-of-competition drug test.
The news was first reported on Twitter by ESPN's Brett Okamoto:
Brett OkamotoFormer UFC heavyweight champion Fabricio Werdum has been notified of a potential anti-doping violation by USADA, stemming from an out-of-competition sample collected on April 25.
As of this writing, it is unclear what Werdum has been flagged for (which is standard USADA protocol).
