David Howman, the director general of the World Anti-Doping Agency, said Tuesday that their policies would not prohibit former UFC middleweight champion Anderson Silva from competing in the 2016 Olympics in Rio in taekwondo because his failed drug tests did not come under the WADA code.
Silva tested positive for steroids in January before a UFC fight. He has insisted he is clean.

Silva has been temporarily suspended by UFC and could be further sanctioned by the Nevada Athletic Commission, a ban the UFC would respect.
He and Brazilian taekwondo officials are planning a news conference Wednesday about his hopes of participating in his home country's Olympics next year, which the national federation has called a "wonderful possibility."
David Howman said the decision on whether Silva could take part in the 2016 Games would need to come from taekwondo's international governing body.
"We're going to have to really say it's at their discretion," he said. "I'm sure they'll exercise it with some care."
Howman plans to meet with UFC executives in coming days. As for boxing, he called it "a world unto its own" that the U.S. Anti-Doping Agency is attempting to deal with.
"It's broken into several states where licenses are given and there are so many events, each of which has its own rules, that unless they coordinate and come together as a group, it's very difficult for a program to be run," he said.
