Forest will likely be unhappy with the decision. The Premier League club last week appointed former top-flight referee Mark Clattenburg as a referee advisor, hoping to improve communication with the PGMOL.
Clattenburg was sat alongside PGMOL chief Howard Webb at the City Ground and might have tried to get answers from his former colleague. Gibbs-White posted the images alongside each other but did not comment further.
Manager Nuno Espirito Santo said afterwards: “[Disappointing] for all of us, for our fans, for us as a team. We played good. We had good situations and we’re disappointed to lose at the end. Not too many differences. Both teams had chances, both teams were organised. It was a good game.”
