Middlesbrough winger Viktor Fischer is out of the club's festive programme after picking up a knee injury.
Head coach Aitor Karanka confirmed that the damage the 22-year-old suffered during Saturday's 3-0 Premier League victory over Swansea will sideline him for up to three weeks.
Karanka told the club's official website, www.mfc.co.uk: 'He's going to be out for another two or three weeks at least.
'He's a good lad and an important player in the changing room.
