Crystal Palace boss Neil Warnock claimed West Brom's Craig Dawson got away with "assault" after his challenge on Julian Speroni.
The Palace goalkeeper was taken out by Dawson when Victor Anichebe scored to ignite the Baggies' recovery as they fought back to claim a 2-2 draw.
Saido Berahino's injury-time penalty completed Albion's comeback at The Hawthorns after Palace eased into a 2-0 lead.
Brede Hangeland and Mile Jedinak's penalty had put Palace in control but Warnock was furious with Dawson, comparing the incident to Peter Murphy's challenge on Bert Trautmann in the 1956 FA Cup final.
That infamous incident left the former Manchester City goalkeeper with dislocations to five vertebrae in his neck and meant he missed a large part of the 1956-57 season.
Warnock said: "It's almost an assault, how one of the four officials can't be in a position to see that. Dawson had smashed him in the face and I am lost for words.
"He's had a two- or three-yard run up and smashed him in the face. No wonder Julian is a bit groggy. He wanted to carry on.
"I've had enough talking to the FA. I have not seen something like that since Bert Trautmann.
"I can't say anything about the referee or I get fined and I don't want to because I thought he had a cracking game but he had made two or three really bad mistakes."
Referee Mark Clattenburg also failed to give Palace a penalty before Jedinak's spot-kick when Wilfried Zaha looked to have been fouled by Dawson.
Warnock said: "You can't win, we had four or five surrounding the referee last week and we were told that was wrong. He had a good game but two, maybe three, decisions went against us and it's cost us."
Warnock insisted he knew little of the morning claims a billionaire American investor Josh Harris was in talks to buy the club.
He added: "I only know what I have read. I will be speaking to the chairman but you have to ask him."
West Brom head coach Alan Irvine admitted he had to get angry with his side after their first-half no show.
He said: "They did see another side to me, one which doesn't come out very often but has to come out from time to time.
"I was bitterly disappointed with the first 32 minutes of the game. We conceded the penalty on a counter attack but for the first 32 minutes we were awful. After that we did what we were supposed to be doing and we eventually got a reward for that."
Anichebe scored his first goal of the season after recovering from a groin injury and Irvine felt he played a major part.
He added: "There's no doubt Victor made a difference and before the game I thought we might need him. Having watched Palace and looked at their strengths and the way they are able to play I felt Victor would be needed at some point."
