\Since the announcement of their fight at UFC 152, BJ Penn and Rory MacDonald have both come to an agreement numerous times to undergo VADA (Voluntary Anti-Doping Association) drug testing for their bout. However, for about a month or so, this agreement has been in a delicate balance. VADA wanted to make the results public before the bout, but then that opened a big can of worms. Penn didn't want the results released prior to the bout, and it is hard to imagine that the UFC would want this either, as it could put a highly promoted matchup in jeopardy.

Today, however, VADA officials announced that both Penn and MacDonald have agreed to the testing, and it has been given the green light for their bout. They will be the first fighters in UFC history to undergo this kind of drug testing. The results of the testing are going to be sent immediately to the Association of Boxing Commissions (ABC) and the Ontario athletic commission. Despite the possibility that this may put the bout at risk, MacDonald's manager has said that he has yet to see any concern from the UFC.

The VADA testing consists of random urine and blood drug tests spread over an eight week period in the lead up to their bout. They will be on the main card of UFC 152 on September 22nd in Toronto, Canada.
