Gareth Bale's injury woes may be set to continue as the Real Madrid star was withdrawn at the half in his side's scoreless draw with Atletico.
The forward had gotten off to a fine start in La Liga, with three goals and two assists in five games, as well as a tally in the Champions League.
But held off the scoresheet in a disappointing 3-0 loss to Sevilla midweek, Bale looked to get back among the goals in the big clash against their local rivals.
Yet his match would be ended early as though he made it through the first 45, Dani Ceballos came on to replace him at the start of the half.
