Manchester United midfielder Marouane Fellaini has been ruled out of action for the next six weeks after undergoing wrist surgery over the weekend, according to reports.
The former Everton star, who cost the Red Devils £27.5m at the end of the summer transfer window, had been carrying his injury for several months.
In October, United boss David Moyes confirmed that Fellaini did require an operation, but that it could be delayed for up to two years.
"It is quite a bad wrist injury," the Scot told reporters. "There is a bit of bone and ligament sticking out."
However, the Belgium international has gone under the knife much sooner, with Moyes's decision possibly influenced by the return of midfielder Darren Fletcher.
Fellaini has only featured in eight of the Red Devils' Premier League matches this season - and has failed to open his account for his new employers.
The 26-year-old will now miss the rest of the festive campaign, but could return towards the end of January.
