Deportivo have only just welcomed Ze Castro back into action but could lose him to another injury after this weekend.
The Portuguese centre-back was forced off midway through his side’s 2-1 defeat at Rayo Vallecano yesterday afternoon through injury.
The 29-year-old is thought to have damaged the adductor muscle in his right thigh and faces an anxious wait for tests to ascertain the extent of any damage done.
Ze Castro was only making his second appearance of the season since returning from a previous long-term thigh injury.
The defender damaged the quadriceps in his right thigh in late May during one of the final games of last season and aggravated it further during pre-season.
Given a clean bill of health at the end of August, Ze Castro had to wait a month to return to action, as Coach Jose Luis Oltra only selected the player for his first appearance of the season last weekend at Real Madrid.
