UFC strawweight Amanda Ribas placed on temporary suspension by NAC due to positive ostarine test

UFC strawweight Amanda Ribas was placed on temporary suspension Monday morning at a meeting of the Nevada Athletic Commission.

Ribas (6-1) tested positive for the banned substance ostarine in a random June 7 drug screening collected by USADA, the commission revealed. That test, announced earlier this month, resulted in the UFC removing Ribas from her planned Octagon debut against Juliana Lima at the Ultimate Fighter 25 Finale on July 7 in Las Vegas.

Ribas is not the first UFC fighter to fail a drug test due to ostarine. Since the inception of USADA, several fighters have tested positive for the performance-enhancing substance, including Tom Lawlor, Tim Means, and Carlos Diego Ferreira.
