A Mallorca supporter was captured aiming racist abuse at Aurelien Tchouameni after the Real Madrid star's winning goal on Saturday.
Tchouameni scored in the 48th minute with a thunderous shot from distance to beat Mallorca goalkeeper Predrag Rajkovic.
The midfielder wheeled away to celebrate his 30-yard screamer, his third goal of the season.
Real Madrid players joined Tchouameni in celebration by the corner of the pitch with cameras from Spanish broadcaster picking out alleged monkey gestures by a home fan.
The supporter's face was pixelated by the broadcaster.
Real Madrid players appeared unaware of the alleged racist abuse in their 1-0 victory.
The incident further fuels the debate swirling around racism in Spanish football, with 16 incidents of racist abuse against Real Madrid's Brazil winger Vinicius Jr reported to Spanish prosecutors by LaLiga in the last two seasons.
Earlier in April, Getafe were ordered to partially close their central stand for three matches following racist and xenophobic abuse suffered by Sevilla manager Quique Sanchez Flores and player Marcos Acuna in a LaLiga game.
The same day, a Spanish third-division match between Rayo Majadahonda and Sestao River was suspended after Rayo's Senegalese goalkeeper Cheikh Kane Sarr confronted a rival fan who he said was racially abusing him.
Movistar earlier this week fired analyst German Burgos over comments he made about Barcelona winger Lamine Yamal.
The former Argentina goalkeeper and assistant manager at Atletico Madrid, said 'if [professional football] doesn't go well for him, he could end up at a traffic light.'
The comment, which has been interpreted as a reference to people who stand at traffic lights asking drivers for money.
Burgos comment led to Barcelona and PSG refusing to give interviews to the Spanish rights holder after their Champions League quarter-final first leg.
The remark by Burgos was made as 16-year-old Spanish international Yamal, who was born in Spain to Moroccan and Equatorial Guinean parents, did kick-ups during the warm-up and the programme host praised the teenager's skills.
Burgos then apologised saying that 'sometimes humour gets you into trouble' and the 54-year-old later posted a more extensive apology on his social media stressing his 'intention was not to denigrate Lamine Yamal, quite the contrary.'

Tebas is a very unserious president, if you can't handle racism or make an example of those Racists you deserve to re-sign

To all these haters, I guess Tchouameni also provoked the opposite fans just like Vini did, right? I see no reason why you guys are just so blind to see that they're just racists among the faithful fans. Only when it hits your favorite players as hard as it does to Vini, only then will you be in your right senses. I guess
