Arsenal have reportedly suffered yet another major injury blow after Aaron Ramsey was ruled out for up to a month with a hamstring injury.

According to the Daily Mail, the midfielder who was substituted during half-time in the midweek Champions League game against Galatasaray due to a tight hamstring, has not recovered in time to face Newcastle United on Saturday.

The report claims that the Welsh star, who was just beginning to get back to form and hit the ground running is set to be sidelined for the entire Christmas and New Year period, and will miss crucial Premier League fixtures against Liverpool, QPR and West Ham United.

Arsene Wenger has stated after the game in Turkey that the midfielder was substituted as a precaution and was confident that he will recover ahead of the game against Alan Pardew's team.

However, the manager has now revealed that the former Cardiff City player has not recovered from the injury and despite a scan, he is not sure about the extent of the injury.

"We got the scan last night, I don't know enough to give the extent of his injury," Wenger said, as quoted by the BBC.

The north London club are facing a major injury crisis during the most crucial period of the season, with the club missing key players in defence and midfield. Jack Wilshere is out for three months and skipper Mikel Arteta has also failed to recover from his calf injury leaving the Gunners light in midfield.

This has prompted the Frenchman to recall Francis Coquelin from his loan spell at Charlton Athletic, to aid Mathieu Flamini marshall the Arsenal midfield.

Wenger, who was hopeful that Ramsey will be fit for the game, admitted that he only decided to call the French midfielder back from his loan, following a text from the Welsh international regarding his unavailability for the Newcastle game.

"He told me yesterday he was very positive and much better and that he would play, then he texted me late last night and said he was out. I called Coquelin back from Charlton," the Gunners boss said, as quoted on Arsenal's official site.
