Real Madrid’s Brazilian defender Marcelo could miss the Spanish giants Champions League trip to AS Roma next week after suffering a dislocated right shoulder, the club confirmed on Tuesday.

The 27-year-old Marcelo, who has become a key element in new coach Zinedine Zidane’s side, picked up the injury during Sunday’s 2-1 La Liga win at Grenada.

The club said in a statement that the defender had undergone tests on Tuesday but did not give details of how long he would be out for, stating simply that it would depend on the “evolution” of the injury.

According to the Spanish press, Marcelo could be sidelined for three weeks, meaning he would miss Saturday’s La Liga game against Athletic Bilbao and the European last 16 away leg tie at Italian club Roma on February 17
