Jack Wilshere has already been forced out of an Arsenal game by injury and could be ruled out for another week, according to a report.

Hayters sports reporter Simon Collings shared the news via his Twitter account that the England midfielder missed Arsenal’s 3-1 pre-season friendly win over Chivas in the US on Sunday night after suffering a knee problem.

Wilshere has an extensive injury record starting back in 2009 when the 24-year-old suffered the first of many serious ankle injuries.

Collings reported that Wilshere’s latest injury should not keep him out for too long, but there will be fears among Arsenal fans it could end up being something more serious.

Wenger’s delicate talisman has gone on to need ankle surgery, a knee operation, suffered a hairline foot fracture in 2009 and then missed a staggering 47 matches over 247 days last season after a hairline crack in his calf bone.

The former Bolton loanee has been sidelined throughout his career for 890 days missing out on 154 matches for the Gunners.

He will now be hoping to recover quickly in time for the north Londoners’ first game of the season against Liverpool in two weeks time and go on to have a full, uninterrupted season at the Emirates.

In other Arsenal team news, goalkeeper Petr Cech has challenged new signing Rob Holding to bridge the gap left by the injured Per Mertesacker at the start of the Premier League season.
