Real Madrid have confirmed that left-back Marcelo has been sidelined with a dislocated shoulder.
The Brazilian suffered the injury during his side's 2-1 victory at Granada on Sunday.
It has not been confirmed how long Marcelo is expected to be on the sidelines for, but the defender is likely to miss the first leg of the Champions League last-16 tie against Roma on February 17.
A statement from the club read: "After tests carried out today on the player Marcelo at the Sanitas La Moraleja University Hospital, he has been diagnosed with an acromioclavicular shoulder joint dislocation. His recovery will continue to be assessed."
Marcelo has made 24 appearances for the club this season, scoring two goals.
