By now, Dominick Cruz is probably immune to the many verbal attacks Urijah Faber has dished his way over the years. After all, the two have one of them most bitter rivalries in all of mixed martial arts (MMA) that spans nearly a decade; therefore, there isn't anything "California Kid" can say to rattle "Dominator" at this point.
However, Cruz was surprised to hear Faber slam his own former training partner and friend, T.J. Dillashaw, after Faber insinuated during a recent interview that Dillashaw was dabbling in performance enhancing drugs (PEDs). As Cruz revealed on "The MMA Hour" (via MMA Fighting) even if you have beef, you don't slam your ex-friends.
