All 22 fighters who competed at UFC 184 were blood tested for banned substances, and all 22 fighters tested negative, California State Athletic Commission Executive Director Andy Foster informed Sherdog.com on Tuesday evening.
The CSAC received results from the blood tests conducted at the Feb. 28 event this week. It marked the first time in commission history that all fighters from a card were blood and urine tested.
All the fighters’ urine samples, which were received last week, tested negative for performance enhancing drugs and drugs of abuse as well. In addition, on carbon isotope ratio (CIR) test was performed, and that result came back clean as well.
UFC 184 took place at Staples Center in Los Angeles and saw Ronda Rousey retain her bantamweight crown with a 14-second submission of Cat Zingano in the evening’s main event. In the co-headliner, former boxing champion Holly Holm took a split decision over “TUF 18” veteran Raquel Pennington at 135 pounds.
