Due to kick off at 20:45 CET on Sunday night, damage to the Estadio Balaidos roof has been considered too great to fix at short notice with no date given for the rearranged game.
Real had proposed the fixture be moved to another venue or played in a partially closed Balaidos, but a report from the Vigo city council has been the catalyst for LaLiga to make the postponement official.
"According to the City of Vigo report, the agency believes that Estadio Balaidos cannot guarantee the safety of supporters and players for tomorrow's match," read an official league statement.
"Therefore, having received this information, LaLiga and Celta Vigo have transferred this report to the RFEF.
"LaLiga will propose possible dates to rearrange the game, listening to the opinion of the clubs and the television operators, so that the RFEF can decide, by the proper procedure, to confirm the new date once delegated to the Competition Committee."
Meanwhile, an announcement is not yet forthcoming over the Wednesday night Copa del Rey semi-final when Celta are due to host Alaves, who have asked for that game to also be called off.
Luis Enrique: Was Messi unhappy at being subbed? I'm not telling you
t was a pleasantly comfortable afternoon for Barcelona as they ran out 3-0 winners over Athletic Club yet Luis Enrique refused to comment on whether Lionel Messi was unhappy after being withdrawn.
The Argentine enjoyed a historic afternoon in which he became Los Cules' most proficient ever free-kick taker, his fine effort flying into the net just before the half-time break, taking him to 27 minutes from set-pieces, just ahead of Ronald Koeman.
However, he was then substituted in the second half, his first withdrawal of the LaLiga season, and it seemed as though he wasn't too happy.
Enrique was quick to rebuff this in his post-match press conference as he made clear he was unwilling to help further a story in the media.
"I will not comment, you always want the story but I don't want you to write this, I'm not going to give you this information," he explained.
Prior to kick-off it was expected that the Basque club would provide their Catalan opponents with a far more competitive afternoon and the Spanish coach reiterated that despite the three goal cushion, his team had to work hard for the victory.
"Against Athletic Club it is never an easy match, no matter what the result their high pressure means there are one-on-one battles across the pitch but we managed to create chances and adapt to the situation."
Aleix Vidal continued his resurgence after being handed another starting spot and he added a goal 20 minutes from time, but Enrique was forced to make clear why he wasn't a regular starter.
"It depends on the match and what we are looking to do specifically," he continued.
"Against Real Betis I brought Aleix on later because he has the ability to come on and change things."
It was also a match to remember for the much-maligned Paco Alcacer who managed to register a goal after a torrid opening six months to his career with the Catalan giants.
On the topic of the former Valencia striker, the Asturian coach was quick to show his delight with the forward's contribution.
"I am happy for Paco not just because of the type of player he is but also because of how he is as a person," he said.
"I always have a special empathy for individuals who are keen to succeed."
Barcelona's forwards are wonderful individual talents but seldom do they shirk defensive duties, and following Saturday's victory Enrique was keen to point that out.
"I think the players have shown that to win titles you have to attack and defend," he noted.
"Leo, Paco and Neymar have all managed to press and make the opponent play in difficult conditions.
"To keep a clean sheet against Athletic Club is a sign we are progressing in the way we want."
Conte celebrates Hazard's wonder goal by throwing himself into the Chelsea crowd
The main attraction at Stamford Bridge these days isn't necessarily the performance on the pitch, as Antonio Conte continues to show his emotion on the touchline like no other.
Saturday saw Eden Hazard dribble his way through the Arsenal backline to give the Blues a two-goal lead a 3-1 win against their local rivals and such was the adrenaline pumping through the Italian coach, he jumped into the stands to celebrate with the home fans.
It's not the first time that Conte has revelled in the moment, either, with the scene harking back to his infamous leap atop the Stade de France dugout roof when his Italy side beat Spain at Euro 2016.
Torres: I play every match as if it was my last
Atletico Madrid returned to winning ways on Saturday evening thanks to a Fernando Torres brace and the 32-year-old striker explained that he aims to give his all in every match he plays.
He had only scored three goals so far this season before the Leganes outing, but added a couple more to his tally and is excited for the next few months of the 2016/17 campaign.
"I am very happy ahead of the last stretch of the season, which is the best part," the striker said after the full-time whistle.
"As I've said, I play every match as if it was my last and I try to enjoy every minute."
Having impressed from the bench last Wednesday's Copa del Rey first leg against Barcelona, El Nino was given a start in this league game and was glad Los Rojiblancos carried that second half performance forward.
"It was important to win and keep up the momentum from the second half of the Copa match," he explained.
"You could see today that the team wanted to press high and leave everything on the pitch.
"Then with the score at 2-0 there was less rush as the game was on the right track and we have a match coming up on Tuesday."
Looking ahead to that test at the Camp Nou, Torres was not fazed by the quality of Barcelona and the fact that the Blaugrana have a 2-1 advantage.
"We need to enjoy today's match and then forget about it quickly," the player said. "Tuesday's match will be very difficult, but that is what we like.
"We feel the emotion of the fans who were supporting us."
Barcelona concerns after Pique forced off against Athletic Club
A thigh injury saw Gerard Pique removed from Barcelona's win over Athletic Club on Sunday afternoon, with the center-back now a doubt for the Copa del Rey semi-final with Atletico Madrid.
However, the situation is less than clear cut without official confirmation as Pique was also perilously close to a second yellow card, having been booked in the 22nd minute of the 3-0 victory.
Taken off at half-time for Javier Mascherano, Luis Enrique was soon forced into another change thanks to Rafinha receiving a nasty cut to his eyebrow 10 minutes into the second period, the Brazilian replaced by Ivan Rakitic.
