Paulo Filho will not defend his WEC middleweight crown against Chael Sonnen on March 26, his manager, Jorge Guimaraes, told Sherdog.com.
“We tried our best with Filho, but it didn't work and he'll not fight in the WEC,” Guimaraes said. “He tried with all his effort to accomplish the title defense, but he realized he couldn't do it due to chemical dependence and depression.
