LONDON (AP) Arsenal manager Arsene Wenger says midfielder Jack Wilshere has fractured his left fibula and will face ''a few weeks out.''

Wilshere sustained the injury after a training ground collision last week but the extent of the damage was only revealed Thursday.

Wenger says ''I had a bad surprise because it is a hairline crack in his fibula'' and that ''there is minimal damage apart from bone damage.''

He missed five months of last season after surgery on a left ankle injury sustained against Manchester United in November.
