Representatives for Rafael "Feijao" Cavalcante want to confirm the fighter tested positive for stanozolol prior to a May 19 Strikeforce event in San Jose, Calif.
They have asked the California State Athletic Commission to screen him again.
CSAC Executive Director George Dodd informed MMAjunkie.com (www.mmajunkie.com) that Cavalcante's "B" sample from his drug test following "Strikeforce: World Heavyweight Grand Prix Final" will be tested for performance-enhancers and drugs of abuse.
Additionally, Cavalcante's camp has requested that one of its representatives "view the opening" of the sample and "possibly the lab analyzing the sample," Dodd wrote in an email.
MMAjunkie.com initially reported that Cavalcante had filed an appeal but later learned that the fighter's camp will decide what action to take after the second test, which is expected to take place June 26. The CSAC employs a World Anti-Doping Agency (WADA) test facility at UCLA in Los Angeles.
