Arsenal and England have been rocked by the news that forward Theo Walcott will miss the rest of the season and the FIFA World Cup™ due to an anterior cruciate ligament injury to his left knee.

The Gunners confirmed on their official website that Walcott is likely to be out for at least six months as a result of the problem sustained in the 2-0 FA Cup third-round win over Tottenham Hotspur at the weekend.

Walcott was taken from the field on a stretcher - and was subsequently pelted with objects thrown from the away end - after appearing to jar his knee when making a tackle during the closing stages of the encounter although the injury has turned out to be more severe.

"After coming off injured in Saturday's 2-0 win against Tottenham Hotspur, the club regrettably announces that Theo Walcott has sustained a ruptured anterior cruciate ligament of his left knee," said the statement on the club's official website, www.arsenal.com.

"Theo will have surgery in London in the near future and is expected to be out for at least six months, therefore missing the remainder of the season and the World Cup in Brazil in the summer."
