On FOX Sports 1 on Tuesday, White spoke on the matter, saying it wasn't easy to end Sonnen's TV job with the UFC and FOX.
"You know, its never easy making decisions like this," White said. "You know, Chael is a person I personally care about, I know a lot of people at FOX care about him too. The guy had four banned substances in his system. Four banned substances in his system leading up to a fight here in Las Vegas.
"It's a tough one," White said. "It's one of those hard decisions you gotta make. It was definitely a hard one. It was something we had to do."
