Argentine central defender Ezequiel Garay has joined Real Madrid's long injury list for Sunday's derby at home to Atletico Madrid, the club said.
Garay has a thigh muscle problem and will miss the game for the league leaders, who are also deprived of Brazil playmaker Kaka, Frenchmen Karim Benzema and Lassana Diarra, Dutch midfielder Royston Drenthe and Portugal defender Pepe.
Real are ahead of Barcelona on goal difference. The Catalans, who play at Real in two weeks, can go three points clear with a win at Real Mallorca later on Saturday.
