UFC 147 drug test results come back clean for 'Franklin vs Silva 2' on June 23 in Belo Horizonte

UFC 147 drug test results are in from the Ultimate Fighting Championship (UFC), who today confirmed via Sherdog that all 22 fighters tested for illegal/banned substances after competing at the "Franklin vs. Silva 2" pay-per-view (PPV) event back on June 23, 2012 in Las Vegas have all passed with flying colors.

When the UFC holds events in countries which don't have regulatory bodies like in Japan, the UK or Brazil, they run the tests themselves.

Each combatant was screened for performance enhancers such as steroids and drugs of abuse like cocaine and marijuana, among others.

Results from these battery of tests all returned negative.

UFC 147 featured a rematch between veterans Wanderlei Silva and Rich Franklin. Franklin had stepped up in place of an injured Vitor Belfort, who coached against Silva on the inaugural season of TUF Brazil.

Franklin survived nearly being finished by "The Axe Murderer" in the end of the second round to outstrike and handily win a decision in hostile territory.
