The UFC working to sign a "mind boggling" middleweight

According to sources the UFC is close to signing what Dana White called a "mind boggling" middleweight fighter. Many people believe that the fighter in question is either Cung Le or Ricardo Arona who has fought at 185 in the past. Either way it's gonna be interesting to see if this is really something interesting or just Dana White extremely overhyping ordinary news as he has done in the past.
