The UFC dramatically stepped up their battle to rid the sport of performance enhancing drugs yesterday by announcing comprehensive out-of-competition testing for every fighter on the roster and increased suspensions to at least 2 years for those who get caught.

Afterwards a number of current UFC fighters came out in support of the UFC’s new drug testing policy, including Georges St. Pierre who had indicated recently that he would only consider returning to the sport if the promotion improved their testing procedures.

“Very happy to learn about the UFC announcing a new comprehensive random PED testing,” the former welterweight champion, who vacated his title in 2013, wrote on Twitter after hearing the news. “Clearly a big step in the right direction for our sport. Can’t wait to get more details about the actual protocol, 3rd party testing agency and new sanctions.”

Meanwhile, current woman’s bantamweight champion Ronda Rousey spoke to FOX Sports 1 to give her thoughts on the announcement.

“I believe with a combat sport like UFC, it’s so important – so much more important than any other sport [to get properly tested] – because it’s not just fairness,” Rousey said an the America’s Pre-Game show. “It’s the safety of the fighters. And keeping the sport safe is what makes it possible for us to do it.

“I gave my opinion [to the UFC], and I’m glad it didn’t fall on deaf ears. These guys are smart, they know how to do business. The No. 1 thing they can do to protect their investment is to make sure the sport endures.”
