Jack Wilshere will be out for up to six weeks after suffering another shattering injury blow, Football Insider sources understand.

The Arsenal midfielder has learned that he faces an extended spell on the sidelines following a setback in his recovery from a hairline fracture of his left fibula.

Sources have told Football Insider that Wilshere will be out for four to six weeks, ruling him out to at least mid October and potentially November.

It is another devastating blow for the injury-plagued midfielder, who missed five months of last season with ankle ligament damage.

He has not played in the 2015-16 season after getting injured in training a month ago although the initial hope was that the latest in a series of injuries for Wilshere would not prevent returning him straight after the international break.

However, Arsene Wenger admitted at his media briefing on Thursday that his hopes of having Wilshere available to face Stoke on Saturday had subsided.

“I have not seen Jack Wilshere in the last two or three days,” Wenger said. “He is progressing slowly and I can’t tell you much more about it.

“It is slower than expected as I expected him to be back and available after the international break, but unfortunately he will not be available for Saturday. He had a little setback.”

The Wilshere injury is another blow for Arsenal after it emerged that Danny Welbeck is expected to be out for six months after undergoing knee surgery.

Wenger admitted that Welbeck will be sidelined until at least Christmas but the likelihood is that the England international will not play again until March.
