Substitute David Beckham was booked for diving in Real Madrid's 1-0 win over Real Betis on Saturday - as his side moved to the top of the Primera Liga.
Beckham was on the bench for the second successive match
The former England captain, suffering from a virus, was on the bench for the second successive game - for the first time since he moved to Madrid in 2003.
After replacing Jose Antonio Reyes in the 67th minute, his first act was to receive a yellow card for simulation.
Mahamadou Diarra headed home after seven minutes to seal the win for Real.
It was Diarra's first goal for Madrid - but their victory was marred when Brazilian right-back Cicinho was stretchered off in the 30th minute.
It was later confirmed that the 26-year-old defender would need an operation after tearing the cruciate ligament in his right knee.
Although the victory took Madrid to the top of the table, any one of four teams could knock them off the summit during Sunday's matches.
