The referee who sent off Jude Bellingham in Real Madrid's match with Osasuna could face severe sanctions, including a five-year ban, after the Spanish Football Federation (RFEF) launched an investigation into a potential conflict of interest.
Martinez Munuera, the referee in question, is under scrutiny for his private business dealings, which may conflict with his role as an official.
The investigation will examine whether Munuera's external interests have influenced his decision-making on the pitch.
The sanctions for a conflict of interest can range from a €100,000 fine to a five-year disqualification from officiating.
Munuera has not been assigned any matches for the time being, and it remains unclear whether he will be allowed to officiate next weekend.
The investigation comes after Munuera's controversial decisions in the match, including the sending off of Bellingham for using foul language and the awarding of a penalty to Osasuna, which led to a 1-1 draw.
