Arsene Wenger has confirmed that Jack Wilshere has a hairline crack to his left fibula.

The England international sustained the injury during an accidental collision in training and it is expected to keep him out of action for several weeks.

“The information you have heard about Jack Wilshere is right,” Wenger told Arsenal.com.

“I had a bad surprise because it is a hairline crack in his fibula that makes him a few weeks out.

“There is minimal damage apart from the bone damage - there is no damage at all apart from that. It was a collision in training and it was all completely accidental.”

Wilshere will continue to be assessed and treated by the Arsenal Medical Team.
