West Brom secured a 1-0 victory over Brighton to give their Premier League survival chances a boost, but it was referee Lee Mason's controversial decision to rule out Lewis Dunk's first-half free-kick which took centre stage at The Hawthorns
Kyle Bartley gave West Brom the perfect start, heading home Conor Gallagher's corner in the 11th minute, before Pascal Gross's spot-kick for the visitors struck the crossbar eight minutes later after Okay Yokuslu was adjudged to have handled in the penalty area after a VAR check
Then came an extraordinary moment and one Mason will want to forget
Brighton thought they had levelled in controversial circumstances when Dunk curled in a quick free-kick from the edge of the penalty area
 Referee Mason blew his whistle - before quickly blowing again - but in between, Dunk had taken a quick free-kick and scored while Sam Johnstone was still lining up his wall
Mason appeared to rule the goal out straight away but after Brighton's players surrounded him to complain, the referee eventually gave the goal - only to finally reverse his decision after a chaotic few minutes and pull the game back for the visitors to retake their initial free-kick
The drama continued into the second half at The Hawthorns and you could not keep Mason out of the game as the referee awarded Brighton another penalty after Dara O'Shea brought down Gross
Gross stepped away from penalty duties after missing earlier in the game, but substitute Danny Welbeck fared no better, crashing his spot-kick against the post as West Brom survived again
Sam Allardyce's side held on to take a remarkable three points which hands them a lifeline in their bid to stay in the Premier League, while defeat drags Brighton, who will be wondering just how they lost the game, right into the relegation mix
However, the spotlight remains on the standard of refereeing in the Premier League after another controversial incident for the officials in what has been a season full of them
28:  Gallagher bundles over Mac Allister right on the edge of the West Brom penalty area
 A chance for the visitors to respond
29:  Dunk takes an early free-kick and he puts the ball in the back of the net while Johnstone is still lining up his wall
 The referee appears not happy with the quick free-kick and the goal will not stand
 However, it appears Lee Mason did blow his whistle, so surely the goal should stand! Brighton are not happy! Hang on, the goal now appears to have been given! What is going on here?West Brom are now furious! There will also be a VAR check
32:  This is a real mess! The goal has now not been given! Confused? Well, so am I!33: The referee has gone over to the touchline and he has explained to both managers what has happened
 It appears he did blow his whistle, but there was another blast of the whistle before the ball hit the back of the net
 The game will be restarted with the free-kick
 Just to clarify, it's West Brom still leading through Bartley's early goal if you'd forgotten
35:  Dunk strikes the free-kick again, but this time Johnstone is ready and makes the save
We move on but that's certainly not the last we'll hear of that incident
West Brom boss : "The referee blew the whistle twice so that was why it was disallowed
 Lee Mason came over and explained the situation regarding that - the only way we can avoid it is to put someone on the ball and don't move back until the referee moves you back
 I thought everybody had to get set
"Brighton boss "As far as I know, Lewis Dunk asked to take the free-kick quickly and the referee said yes
 In between that, there was another whistle
 I don't know what that whistle was for
 It would be nice for a bit more clarification
 I don't know what the second whistle is for
 I don't understand that
"The confusion is on the pitch and it gets worse when someone outside this area is making the decisions
 It is what it is
 We've not helped ourselves with the two penalties so I cannot put it all down to that [disallowed goal]
 We need to improve and get better at that [taking penalties]
 We're never going to get two better chances
 We have to stay calm
""It's embarrassing, it's a horrendous decision
 I said to the ref can I take it, he blew his whistle, and I took it
 Just because there was so much pressure from the bench
 Why doesn't he come and speak to the press like me? Never, they hide behind their bubble
"I don't think he knew what he was doing
 He gave the goal, why did he give it? I don't know why VAR was getting involved, he said 'goal'
 you can look on the video if you want
 "Yeah, he did
 Fact
" "It happened that quick, I'm not sure what has gone on, to be honest
 The referee checked it and the people checked it
 It is what it is
"It's nothing to do with us
 It was the ref's decision
 Brighton had two penalties as well and they've not gone in
 It's a massive win for us
" "The ref blew his whistle, he said, to speak to someone in the wall, there was a bit of pushing
 There was a bit of confusion but Lee Mason dealt with it really well and came to the right conclusion
 It was a bit confusing, I don't think it would have been right for them to score like that
"Confusion over a Brighton goal that was ultimately disallowed at West Brom was slammed as a "shameful, disgraceful piece of nonsense" by Jeff Stelling
The  host was in disbelief as Paul Merson described events at The Hawthorns
"This is a shambles
 Lee Mason what have you done?" Stelling questioned, as the  team watched on
"VAR has given no goal and now he is going to look at the screen
 This is a total, utter, shameful, disgraceful, piece of nonsense!"This is the dream team of Lee Mason and Simon Hooper, who is the VAR at the moment
