Brazilian heavyweight Vinicius Kappke de Quieroz has allegedly tested positive for the steroid Stanozolol following his UFC 120 undercard loss to Rob Broughton on Oct. 16 in London.

News of Quieroz's test and subsequent release from the company was first reported by MMAJunkie.com on Tuesday morning, and later confirmed by Marc Ratner, UFC vice president of regulatory affairs. Since UFC 120 took place in England, the UFC acted as its own regulatory body, performing the services typically reserved for state athletic commissions in the United States. Headlining fighters Michael Bisping and Yoshihiro Akiyama tested clean, as did six other randomly-chosen fighters.

Quieroz made his UFC debut in London and was on a four-fight winning streak before falling to Broughton. The Chute Boxe product is a knockout specialist, having notched all five of his career victories by KO. In his fight with Broughton, however, the “Spartan” was unable to put the Brit away early and became noticeably fatigued as the fight wore on. Broughton pounced on the hulking Brazilian in round three and sent him packing with a rear-naked choke.

Stanozolol is an anabolic steroid derived from testosterone, developed in 1962 by Winthrop Laboratories. Unlike many other steroids, which must be injected, Stanozolol may be taken in tablet form. Commonly sold under the name Winstrol, the steroid is sometimes prescribed to treat anemia and hereditary angioedema. The UFC will reportedly release the findings against Quieroz to the Nevada State Athletic Commission, which may affect the fighter's license eligibility in the United States in the future.
