The Brazilian Athletic Commission (CABMMA) announced on Friday that all fighters tested on the UFC on Fuel TV 10 fight card that took place on June 8 at the Ginásio Paulo Sarasate in Fortaleza, Brazil, returned negative test results for illegal drugs, performance enhancing drugs, stimulants and masking agents.
Every fighter on the card submitted pre-fight urine samples. Four randomly chosen fighters submitted post-fight urine samples, as well as main event fighters Antonio Rodrigo Nogueira and Fabricio Werdum.
Werdum defeated Nogueira in the featured attraction by submission.
Leonardo Santos became the second The Ultimate Fighter: Brazil winner by submitting William Macario in the co-main event.
The card set the record for number of submission finishes on a single UFC event with eight. The previous record was six.
