Thiago Silva (14-2) and Brandon Vera (12-5), who first met in a UFC 125 bout that was eventually ruled a "no contest," will fight again on May 15 in Fairfax, Va.

Silva fought fellow light heavyweight Vera and earned a unanimous-decision win at UFC 125 in January. However, the 28-year-old subsequently was scratched from a planned UFC 130 bout with Quinton "Rampage" Jackson when UFC 125 drug-testing results were released.

This past March, Silva was served with a formal NSAC complaint after two separate urinalysis samples revealed a substance that was "inconsistent with human urine," which indicated that he "submitted an adulterated and/or substituted specimen for testing for the urinalysis." Silva's first test was flagged, which prompted further testing by the Sports Medicine Research and Testing Laboratory, which is accredited by the World Anti-Doping Agency.

Meanwhile, Vera was released from the UFC following the loss to Silva but was brought back when the ruling was made. Vera has since registered a win in the octagon, a UFC 137 decision over Eliot Marshall, but has done little to hide his contempt for the man he openly refers to as a "juice monkey."

The UFC is expected to hold an event at this city's Patriot Center, though UFC executives have yet to reveal the venue for the card or where the action will be broadcast.
