"With the support of my family, I have entered into a drug treatment facility," Jones said in a statement released to Yahoo!. "I want to apologize to my fiancee, my children, as well as my mother, father, and brothers for the mistake that I made. I also want to apologize to the UFC, my coaches, my sponsors and equally important to my fans. I am taking this treatment program very seriously. Therefore, at this time my family and I would appreciate privacy."
