“I’m consistently blown away by the product and presentation that Bellator is bringing to the fans,” Sonnen said in Thursday’s press release. “I’m not nearly done competing and I’m coming after everyone, everywhere. I’m not sticking to one weight class either, I fight at ‘Gangster Weight’ and nobody is safe.”
Sonnen was slated to fight Vitor Belfort at UFC 175 in July 2014. He promptly retired from MMA after his first random drug test showed signs of Anastrozole, Clomiphene and human chorionic gonadotropin.
A second random exam revealed Sonnen tested positive for human growth hormone (HGH), recombinant human erythropoietin (EPO) and hCG.
