Julianna Pena doesn’t seem to care about the reasoning behind Mayra Bueno Silva’s failed drug test. She thinks the Brazilian is a “cheat” not matter how it’s explained.

Bueno Silva (11-2-1 MMA, 6-2-1 UFC) revealed Monday that she tested positive for a banned substance ahead of her July submission victory over Holly Holm, but explained it was due to an ADHD medication, and not that she was intending to gain a performance-enhancing advantage.

It’s likely that Bueno Silva’s win over Holm will be overturned and she will receive some form of suspension, but the final decision hasn’t been made. Peña (11-5 MMA, 7-3 UFC) is happy to cast judgement over her fellow women’s bantamweight contender, though, and took to social media to put Bueno Silva on blast (via X):

#CHEATara, living up to your nickname.
Back to being a curtain jerker of an Apex card you go. You fought two 41yr olds this year and you had to cheat in order to get it done. Can’t pass a #drugtest?

Prior to the latest development, Peña and Bueno Silva were both in the running to fight for the vacant 135-pound belt, which was relinquished when Amanda Nunes retired from MMA in June.

It’s clear, however, that Peña thinks Bueno Silva is now unqualified to be granted that opportunity.
