As we've been reporting, Dolph Ziggler appears to have heat on him backstage and is being punished for something he said during an interview during SummerSlam week. It's unknown what it was or what he said.
This shouldn't be confused with an interview he did in Cleveland before a live event, even though he posted on Twitter that he was "in trouble" for it. That interview (and the tweet) were both in-character and took place long after SummerSlam.
We'll keep you posted as we hear more.
