Sam Allardyce's side went into Monday evening's game knowing they had to continue their form from their incredible 5-2 win over Chelsea last week, if they had any chance of avoiding the drop.
The Baggies started extremely well and had the ball in the back of the net inside the first three minutes of the game, when Darnell Furlong's shot was converted by Mbaye Diagne.
The assistant referee instantly raised his flag for what looked a tight offside so VAR had its usual look to decide the outcome.
Lines were drawn as usual and it was adjudged the striker was offside. However it soon transpired that Kyle Bartley was offside but Diagne was actually fine.
Jan Vestergaard's position did make it difficult for the linesman to pick out whether the goal was offside but it seems that the Saints defender also baffled the video assistant referee.
VAR HQ, Stockley Park, explained the decision, claiming, "The position of the camera we couldn't draw a definitive line."
But social media was aghast that the decision, that was quite clear to the human eye one watching the replay, was not overturned.
West Brom did manage to take the lead, just after the half hour mark, as Matheus Pereira scored from the penalty spot after Fraser Forster fouled the forward in the box.
Fortunately for even VAR managed mess that one up!
