Chute Boxe prospect Vinicius Quieroz released by UFC following failed drug test

Following on from a disappointing UFC debut, Chute Boxe fighter Vinicius “Spartan” Quieroz has been released by the promotion, following a failed drug test. As there are no governing bodies in the United Kingdom, the UFC held there on tests. Of the 6 fighters tested, including main event fighters Michael Bisping and Yoshihiro Akiyama, Quieroz was the only one to fail.

Marshall Zelaznik, the UFC’s UK President, revealed that Quieroz forfeited an undisclosed discretionary bonus from the UFC and has also been released from the promotion. As a result, the UFC also have an obligation to inform the Nevada state commission.

Overall, The Spartan is 5-2. His UFC loss, a 3rd round submission to Rob Broughton, ended his 4 fight win streak.

Speaking to MMA JUNKIE, the UFC’s Vice President of Regulatory Affairs, Marc Ratner, spoke about the UFC’s own tests:

“The UFC enforces the same rules and regulations as the Nevada State Athletic Commission and takes this responsibility to the fighters and the sport very seriously.”

Quantities of Stanozolol (also sold under the brand name Winstrol) were found in the fighters system following the fight. It is a popular body building drug, which should only be used when prescriped to treat anaemia and hereditary angioedema. MMA fighters who have also been caught with amounts of the drug in their system include Phil Baroni, Chris Leben and Tim Sylvia.
