Wolves boss Mick McCarthy was critical of the decision that saw substitute Stefan Maierhofer sent off in injury time as Everton grabbed a fortunate 1-1 draw at Goodison Park.
Wolves had been leading through a Kevin Doyle goal, only for Everton's Russia winger Diniyar Bilyaletdinov to equalise in the 88th minute before giant Austria striker Maierhofer was dismissed for a second yellow card.
Maierhofer was involved in an incident with Everton keeper Tim Howard, who looked to push him in the back of the neck and McCarthy said: "The red card was harsh, bordering on downright disgraceful to be honest."
He added: "I felt the first tackle he put in (on Cahill) was a booking for the manner he went into the tackle.
"But this is an intimidating place. (Everton manager) David Moyes is almost playing wide left for them, getting the ball back on as quickly as he can, but I've no problem with that.
"It all creates atmosphere and the crowd are loving it. But for the first incident, Stefan was just booked for his reaction.
"But for the second yellow card he did what I would expect any centre-forward in the world to do and that is to run across the keeper's path to stop him clearing quickly, that is all he has done."
Everton boss Moyes was just relieved to have got a point when for long spells that looked unlikely.
He said: "We are not playing the way we would like, but we got a point regardless when maybe we didn't think we were going to get one.
"We have to keep plugging away, overall we have to come through it to find form and a bit of style."
