Bellingham has been punished despite his club fighting to have the ban overturned - even using quotes from Cristiano Ronaldo to back him up - but the saga has also had negative repercussions for the referee, who was reduced to tears live on radio.
LaLiga official Jose Munuera Montero dismissed the Englishman after an on-field altercation between the pair during Real Madrid's 1-1 draw with Osasuna on Sunday.
Montero accused Bellingham of saying 'f*** you' to him, despite the England international insisting he had instead said 'f*** off'.
The 21-year-old later described the incident as a 'miscommunication', and insisted he had no intention of insulting the match official.
To support Bellingham's claim, Real Madrid used remarks made by club icon Ronaldo over the widespread use of 'f*** off' by footballers in England and how it is not intended as an attack on referees - something he felt was often misunderstood by officials in Spain.

However, the Spanish Football Federation (RFEF) have chosen to punish Bellingham anyway after judging that he displayed 'contemptuous or inconsiderate attitudes towards referees, officials or sports authorities'.
The saga has sparked outrage in Spain, with Los Blancos even believed to have considered leaving LaLiga, who feel the sending off was the latest in a number of decisions to go against them.
What's more, referee Montero is also under investigation by the RFEF's compliance committee for a separate incident, relating to his 'extra-sporting activities'.
The official owns sports consultancy agency, Talentus Sports, whose alleged clients include the likes of UEFA, LaLiga and reportedly football clubs such as Atletico Madrid and Manchester City.

With recent events forcing Montero further into the spotlight, the Spaniard has now spoken out in the wake of mounting scrutiny.
Appearing on Spanish radio show, El Partidazo, on Tuesday the 41-year-old insisted he had 'never, ever,' received payment from a sporting organisation, but revealed his family had faced a barrage of abuse following the weekend's events.
The referee was left in tears live on air as he said: "Today it was my turn, but how long has the committee been suffering these attacks?
"They are vilifying my nephews, they are attacking my nine brothers, my 80-year-old father went to mass today and... I better keep quiet.
"What are we creating? How can we show in a newspaper the barbarities that we are saying? Are we crazy? Are we controlling violence or promoting it? This is getting out of hand. What sport are we creating with football?"
Montero then revealed he had been unable to leave his house after unfolding of recent events, and called for an end to the onslaught of abuse directed at referees.
He continued: "I've been locked up at home all day not believing what's going on, I'm telling you honestly.
"It's very hard and I'm not saying it for me, I'm very strong mentally, very strong, but this is getting out of hand.
"It's for my family, my teammates, the collective, the young referees, the young people who are starting out.
"What sport are we creating with football? Do we want this? I wish I knew who was behind all this because then that would be the next demand I would make."
Montero also revealed that he had received countless death threats following the Bellingham controversy.
The Spaniard added: "Before I received more than 100,000 threatening messages, death threats, insults... what I did was to silence my Linkedin account.
"I am not afraid because I have nothing to hide. My family is the one who is suffering the most, they are very worried. They know they can't ask me to stop, it's impossible.
"I try to calm them down. I put up with this defamation, but my parents don't deserve this."
Real Madrid's Jude Bellingham shown unexpected RED CARD after unheard conversation with referee
Following the decision to ban Bellingham for two matches, the Three Lions star will now miss his side's league matches against both Girona at home, and Real Betis away.
That's despite Real Madrid fighting tooth and nail to get their star man off the hook, including using Ronaldo's old interview to explain why the Englishman's outburst was not directed towards the referee.
A statement from the committee who decided the punishment reads: "Finally and additionally, it is noted, based on the report of the linguistic expert, the public statements in 2018 of a prestigious player such as Cristiano Ronaldo, who played a large part of his professional career in England, and of the many English-speaking professionals, that the expression "f*** off" is commonly used, among other groups, by English players on the pitch, without this entailing any disciplinary sanction by the referees as it is not an offensive or disparaging expression."

Back in 2018, while he was still a Real Madrid player, Ronaldo said in an interview in Spain: "I played in England for many years and do you know what the English often say as a normal expression and nothing happens? The English say 'f*** off' a lot and the referees don't say anything, they don't think you're attacking them.
"If you say it here [in Spain], they send you away. You have to be a little flexible and talk."
