Fulham defender Fernando Amorebieta could be out of first-team action for up to four weeks after suffering a knee injury at Middlesbrough on Saturday.
The Spaniard, 29, came off 12 minutes before the end of the Whites' 2-0 defeat at the Riverside Stadium.
Tests revealed a medial knee ligament injury but it is not expected to sideline Amorebieta for too long.
The former Athletic Bilbao man is expected to return to training in two to four weeks.
