“Dwayne pushed super hard for it. Read last week's issue and this week's. The card changed when Punk & Brock were out and all the dominoes fell. Dwayne already wanted it and they felt they now needed it as well. Felt this was better to change the news flow away from Vince.

Cody was the plan. Dwayne was going to face him later, maybe next year's Mania, maybe Saudi. Shit happens with Vince and Punk, the Vince thing ends up worse than they thought and they changed the plan. I literally didn't know until yesterday that it could change and then I was told it's under lock. But 100% it was Punk vs. Seth and Cody vs. Reigns until Punk got hurt.”
