In an interview with The Record in Mexico, currently suspended WWE star Sin Cara stated that he was told by WWE management that he failed a Wellness Policty test for steroids, but wanted clarification of why he exactly failed. He later stated he would be meeting with Vince McMahon to discuss the issue and told the newspaper that many medications contain steroids and believes an injection he was given by a doctor for pain may have caused the positive test. Sin Cara denied taking steroids adding he wasn’t built like someone who would use them.
