Jude Bellingham, a midfielder for Real Madrid, received a two-game La Liga suspension after receiving a red card in the 2-2 draw with Valencia.
Twenty-year-old Bellingham thought he had scored the winning goal at the Mestalla on Saturday six minutes into stoppage time.
But as the cross was being delivered, referee Gil Manzano blew the full-time whistle.
Bellingham of England is qualified to participate in Real Madrid's Champions League semifinal match against RB Leipzig on Wednesday.
Bellingham allegedly showed "contempt or disregard" for Manzano as Real players and personnel encircled him, according to the Spanish Football Federation (RFEF).
Real was punished 700 euros (£598), while Bellingham, who was making his comeback after missing three weeks owing to an ankle injury, was penalized 600 euros (£513).
The RFEF disciplinary tribunal denied Real's appeal against Bellingham's red card, despite Real's assertion that the referee committed a "error."
"We were annoyed by Bellingham's red card because he didn't say anything insulting," manager Carlo Ancelotti said following the incident. It was annoyance."
Bellingham, who leads Real Madrid in goals scored in the league with 16 this season, will be out for the games on Sunday against Celta Vigo and March 16 against Osasuna.
After the international break, on March 31, he can play against Athletic Bilbao.
On March 23 and 26, respectively, England will play friendly against Brazil and Belgium.
As they prepare for the second leg at the Bernabeu, Real leads Leipzig 1-0 and leads La Liga by seven points at the moment.
