Jude Bellingham was sent off with a straight red card in Real Madrid's game at Osasuna after he reportedly said something inappropriate to the referee.
Referee Jos Luis Munuera dismissed the England midfielder in the 40th minute of Saturday's LaLiga game after Bellingham appeared to complain about a refereeing decision while gesturing with his arms.
The two exchanged words before Munuera pulled out the red card.
Madrid coach Carlo Aneclotti had already received a yellow card for complaining about what he thought was a handball by an Osasuna defender in the host's area that was not punished.
Madrid were 1-0 up after a goal from Kylian Mbapp when Bellingham ran afoul of the ref.
