Nyligen meddelades det att Yoel Romero testat positivt på en otillåten substans, och hans manager Malki Kawa meddelade via ”The MMA Hour” att Romero fått i sig preparatet via felmärkta kosttillskott. Yoel bedyrar nu sin oskuld gällande det inträffade, och så här skrevs det via ”MMAJunkie”:
I think it’s my responsibility when I take something. But I think maybe a public warning would be a fair punishment. When you see the supplement, outside it says it’s clean, you can take it.
My whole entire life, I’ve trained very hard. I abstain from a lot of stuff in life. To reach not just the world title, but also to maintain my family. If I would have committed what they’re saying, I’m running the risk that I can’t support my family. I think more about my family than I do a title. I’m conscious that if I take one of these supplements, they’re going to catch me.
Sist vi såg Romero inne i oktogonen besegrade han Ronaldo ”Jacare” Souza via ett delat domslut, då de möttes under UFC 194 i Las Vegas.
