It looks like the UFC could have some controversy coming down the pipe, as the man who helped exposed the link between a few high-profile baseball players and PEDs provided by Biogenesis has revealed at least one professional Mixed Martial Artist also received an illicit substance from the company. However, no details were provided, and it’s entirely possible the fighter(s) in question were not members of the world’s foremost MMA organization.

According to a report from ESPN’s Outside the Lines, former Biogenesis employee Porter Fischer said athletes from across the sporting world were involved in the controversy. The two biggest names to surface thus far are MLB stars Alex Rodriguez and Ryan Braun.

Biogenesis was housed in South Florida where camps like American Top Team and The Blackzilians set up shop. More information is expected to surface in the coming weeks.
