5 Things you didn't know about Corey Graves 

#2 Corey Graves had a falling out w/ long-time friend CM Punk

CM Punk and Corey Graves

Just how close were Corey Graves and CM Punk? CM Punk held Graves' child even before he did. Graves happened to be on tour when his newborn came into the world and Punk, a close friend whom Graves trusted and respected, went to visit the child even before Graves.

No one expected these two to ever have a falling out, but after Punk's messy public 'divorce' with WWE, he told Graves in no uncertain terms where he stood.

Graves told Fightful,

"It kinda shocked me when I texted him about grabbing dinner because we were in Chicago and he told me he no longer had any interest in being friends with me or anybody related to WWE."

Graves was hurt and could no longer hold back. After Punk's UFC 225 loss, Graves took to social media to lash out at his former friend,

"Maybe abandoning everybody who stood by your side, even when we weren’t supposed to, only to have you turn your back on us wasn’t the right move after all? No anger. Only sadness."

Corey Graves further elaborated in his interview with Fightful,

"I’m simply hurt/pissed off that a guy that I looked like as a big brother-type has turned his back on me and everyone that loved and supported him only because of the name on my paycheck. I’m definitely not the only one. I won’t name names, but there is a large group of us to this day that inexplicably lost a solid friend because of where we work."

In the ultimate dig, Graves even questioned Punk's punk credentials,

"The first rule of “punk rock” is loyalty, and this guy betrayed it all. I still love you, “friend” and I’m sorry you got lost."

Ouch!
