The Norway international, on loan until the end of the season from Zenit St Petersburg,
is sidelined through illness.
With the exception of Hagen and Swedish left-back Erik Edman, who faces a long-term
recovery from a knee injury, boss Steve Bruce has a full squad to choose from.
Tottenham full-back Pascal Chimbonda has a calf strain and is a doubt to face his
former club Wigan at the JJB Stadium.
Goalkeeper Paul Robinson (ankle) is unlikely to feature in the Premier League clash,
while Gareth Bale (foot), Benoit Assou-Ekotto (knee) and Ledley King (knee) will miss the rest of the season.
England Under-21 midfielder Jamie O'Hara is back in full training after a bruised foot.
