Brewster saw yellow after a challenge with Wolves left-back Rayan Ait-Nouri, as United lost 1-0 and were officially relegated from the Premier League.
But replays suggested that Brewster was the victim in the tackle, rather than the aggressor, as the French youngster Ait-Nouri appeared to go over the top of the ball and catch Brewster.
The VAR, Chris Kavanagh, checked the incident and did not advise referee Rob Jones to change the decision, or take a look on the pitchside monitor, so Brewster’s booking stood.
But, according to former Premier League referee Halsey, the former Liverpool youngster could have suffered a lot worse.
“For once, there was a real lack of discussion points from the Premier League this weekend, in terms of decisions from officials,” Halsey wrote in his column for CaughtOffside.
“Don’t get me started on the Super League!
However, on Saturday, in the Wolves vs Sheffield United game, Wolves’ No.3 Rayan Ait-Nouri’s challenge on Rhian Brewster was worthy of a red card in my opinion. It was a potential leg-breaker.
“Referee Robert Jones cautioned Brewster for a poor challenge and not Ait-Nouri, and whilst you could perhaps argue it was a caution, the challenge wasn’t by Brewster but on him.
“It was a serious and obvious error from the official, or a red card challenge. At the very least, the VAR should’ve advised Jones to take a look at the pitch side monitor.”
