UFC 163 Drug Test Results: All 24 Fighters Tested in Brazil, All Return Negative
Jason da Silva-USA TODAY Sports

The drug test results from last weekend's UFC 163: Aldo vs. The Korean Zombie card have been returned from Brazil with every fighter on the card undergoing testing.

According to a release from CABMMA, the Brazilian Athletic Commission, all 24 fighters on the card were tested, and all came back with negative results.

"The Brazilian Athletic Commission (CABMMA) informs that all the fighters who participated in UFC 163 held in Rio de Janeiro on August 3, 2013, were submitted to tests of anti-doping control," the commission stated in a press release on Friday. "The results of these tests did not reveal any illicit drug use, and/or to improve performance, stimulants or substances used to mask the use of the same by any of the athletes who participated in UFC 163."

The Brazilian Athletic Commission is still fairly new by governing body standards, but it is starting to churn out results and testing in an orderly fashion after only a few major UFC shows in the area.

UFC 163 was the latest card to take place in Brazil, and with several more shows occurring there this year, the commission will definitely be busy.

The show was headlined by UFC featherweight champion Jose Aldo, who made another successful title defense by defeating "The Korean Zombie" Chan Sung Jung in the main event.

The co-main event featured a bout between former 205-pound champion Lyoto Machida and Top 10 light heavyweight, Phil Davis.

The next card in Brazil will take place on September 4, when Glover Teixeira takes on Ryan Bader in the main event. CABMMA will be the governing athletic commission for that card as well.
