The Voluntary Anti-Doping Agency (VADA) has said that Chael Sonnen's failed drugs test is the fault of the Nevada State Athletic Commission's (NSAC) drastic rule changes.
A tweet sent last night by the agency read "You can't just tell an athlete to whom you previously gave permission to simply stop testosterone without medical consequences. #MMA #UFC".
This was in reference to the outlawing of Testosterone Replacement Therapy (TRT) that high profile fighters like Vitor Belfort, Chael Sonnen and Dan Henderson had been undergoing.
Of those three, only Henderson has remained 'clean' thus far, with Belfort initially pulling out of the UFC 175 event, where he was to challenge Chris Weidman for the UFC Middleweight title, because he knew he'd fail the drugs test for his fighter's license.
It emerged earlier this week that Sonnen had failed a random spot test, testing positive for anti-estrogenics with the drugs Anastrozole and Clomiphene being the culprits according to reports.
Sonnen has since said that he was on the drugs in order to come down from his TRT use and that it was well-known... except to the commission.
While many medical professionals who've been asked about the case say that Sonnen's reasons for using these drugs are fair and normal, the drugs are prohibited in the sport's world and it's Sonnen's fault for using them.
The tweet sent by the VADA wasn't the only one though. In a series of tweets they took several shots at the UFC and NSAC about the drug testing policies within MMA:
"Current random testing grabbing only a few. If commissions wish to stop the problem,all fighters must undergo testing program. @UFC wake up!"
"Imagine if CIR/IRMS, EPO, hGH done on every fighter? It's the only to start cleaning up dirty sport. Unfair to clean fighters to not institue"
"VADA continues to offer @UFC & NSAC free advice on setting up their own stringent PED-testing program with UNIFORM policies/procedures.#MMA"
"If an athlete has a med condition only treatable with harmful/prohibited substances then they should not be declared fit to compete."
It's not the first time that VADA has been involved in some drama in the UFC. George St-Pierre and Johny Hendricks nearly didn't fight because of Hendricks' issues with VADA, believing that the agency had a bias towards St-Pierre.
They also had issues with Shane Carwin ahead of his proposed fight with Roy Nelson, which resulted in that fight being cancelled because Carwin and his camp believed they couldn't trust the VADA setup due to possible prejudice in favour of Nelson.
Either way, it's been a manic start to the week for UFC President Dana White and it looks like it will only get crazier, especially if VADA succeeds in getting the support of UFC broadcasters, Spike TV and Fox Sports, in cleaning up the UFC with a new drug testing policy.
