Arsenal [ Images ] midfielder Jack Wilshere will be out of action for at least another two months due to an ankle injury, the England [ Images ] international said on Sunday.

"I can confirm I will be out for around 2-3 months. I am working hard in the gym to stay fit and I am gutted but I will be back stronger," Wilshere wrote on Twitter.

The 19-year-old sustained the injury during Arsenal's pre-season tour and missed the first three Premier League matches of the season from which the London [ Images ] club gathered only one point.

Arsenal sold midfielders Cesc Fabregas [ Images ] and Samir Nasri before the end of the last transfer window and, although they signed Mikel Arteta and Yossi Benayoun [ Images ], Wilshere's prolonged absence is another serious blow for beleaguered manager Arsene Wenger [ Images ].
