The Brazilian featherweight, who had the win overturned to a no-contest and was issued a nine-month suspension by the Brazilian MMA Athletic Commission (CABMMA), told MMAFighting.com he required the commission to test the B sample, and will sue the commission if proven innocent.
"CABMMA informed me that the sample B will be tested on July 15," Jason said. "My lawyer is going to Las Vegas to follow the entire procedure. I’m doing everything I can to revert this result. After we revert the result, we will sue CABMMA for (moral and material) damages."
Jason claims he never needed diuretics to make weight for any MMA bout throughout his entire 20-fight career, and believes the false positive could have been caused by an anti-inflammatory he was taking to fix an ankle injury.
"I was taking an anti-inflammatory, and it was really strong," he said. "I have my lawyer, my doctor and my coaches taking care of this for me."
If proven guilty, Jason will be suspended until March 1, 2016, and his UFC record will drop to 4-2 with one no-contest.
