Marouane Fellaini could be sent for a further scan on his injured back, according to Manchester United manager David Moyes.
The former Everton midfielder has been out of action since December 4 and Moyes is eager to get to the root of the problem as soon as possible.
"Fellaini has an injury to his back, which we hoped might have healed up but it hasn't," Moyes told Sky Sports News.
"I am going to get another scan and if it hasn't healed up then I might need to take the decision to get his wrist done as well. We hoped his back would be better in 10 days but he is still feeling it."
Fellaini joined the Red Devils for £27.5m in the summer.
