Djourou may return next month

Johan Djourou has undergone shoulder surgery and will be out of action for at least four weeks as a result.

The Arsenal defender suffered a dislocated shoulder during the Gunners' recent FA Cup quarter-final defeat to Manchester United.

Arsene Wenger announced at the time that he expected the problem to keep the Switzerland international sidelined for the remainder of the season.
That diagnosis was countered by the Swiss Football Association shortly after, as they revealed that they hoped to have Djourou in contention for Euro 2012 qualification duty.
There was never much chance of the centre-half being ready to link up with his international colleagues, but it has been confirmed that he could figure again this term.
Arsenal have revealed that the 24-year-old will be missing for a month, but that would still allow him to play a crucial role in the club's Premier League title bid.
"Johan Djourou has undergone exploratory surgery on his dislocated shoulder, sustained at Old Trafford in the recent FA Cup fixture against Manchester United," read a statement released on the club's official website.
"The club can confirm the positive news that there isn't a need for reconstructive surgery and he will now begin a period of rehabilitation on the shoulder before returning to training in around a month."
