The UFC 184 main event between Ronda Rousey and Cat Zingano is officially a go after both fighters returned negative drug tests administered by the California State Athletic Commission earlier in February.
California State Athletic Commission executive director Andy Foster confirmed the news to FOX Sports on Thursday.
The two fighters had urine samples submitted with a full panel of tests run for performance enhancing drugs under the World Anti-Doping Agency (WADA) code and both Rousey and Zingano showed no signs of any illegal substances.

The tests were conducted at the UCLA Olympic Analytical Lab, a WADA accredited lab, which holds the highest standards for all drug testing worldwide.
With the pre-fight drug tests out of the way, Rousey and Zingano will move forward as the main event for next weekend’s UFC 184 card from the Staples Center in Los Angeles.
Foster also confirmed that both Rousey and Zingano will undergo similar testing on fight night for the same panel of drugs as well as any drugs of abuse, which are deemed illegal when fighters compete in competition.
UFC 184 goes down on Feb. 28 with Rousey and Zingano headlining the card with fellow women’s bantamweight fighters Holly Holm and Raquel Pennington set as the co-main event for the evening.
