Van Persie ruled out for 2-4 weeks

Arsenal striker Robin van Persie has been ruled out for 2-4 weeks with an injury to his left ankle.

The Dutchman suffered the knock during Saturday's 2-1 win at Blackburn and was replaced by Marouane Chamakh in the 35th minute.

He joined up with the Dutch squad ahead of the upcoming 2012 qualifiers against San Marino and Finland, but the national team's doctors gave him the bleak prognosis.

The 27-year-old will definitely miss Arsenal's match against Bolton Wanderers on September 11 and the Champions League encounter at home to Portuguese side Sporting Braga four days later.
