LONDON (Reuters) - Arsenal and England forward Theo Walcott has been ruled out for at least six months after rupturing knee ligaments and will miss this year's World Cup, the club said on Monday.

Walcott suffered the injury late in the 2-0 victory over Tottenham Hotspur in the FA Cup third round on Saturday and he left the field on a stretcher after appearing to jar his knee in a challenge with Danny Rose.
