The Brazilian lateral could not finish the match against Betis (0: 1), and was replaced at the 72 minute of the game.
Earlier it was expected that Marcelo will miss about two weeks, but an in-depth medical examination showed that the defender's problem is more serious.
As reported by Marca, the Brazilian was diagnosed with fibrillation of the muscle of the hamstrings. According to preliminary forecasts, it will take about a month to restore the lateral.
The next match Real Madrid will hold on September 23 at the exit against Alaves.
Previous defeat from Betis commented on the head coach of Real Zinedine Zidane.
