#3 Referees are connected to backstage officials through their earpiece
We've heard many times that Vince McMahon is constantly in the ears of the commentators and keeps telling them what to do and say from backstage. But another interesting fact is that the referees are also connected to the backstage officials through their earpieces.
In one of WWE Network's series, Breaking Ground, WWE officials are shown wearing earpieces to stay in touch with the Chairman and COO (Triple H) of the company who can pass on important information to them during the match.
For example, if there's a change in the ending of the match due to any reason after the match has begun, it's the referees through which the information is passed on to the wrestlers in the ring.
We often see referees talking to the wrestlers in the ring and it is portrayed as if they are warning them to follow certain rules, but next time onwards try to listen carefully as to what the official says to the superstar. Maybe you'll get to hear something interesting.
