Walcott suffered knee ligament damage against Tottenham back in January and was immediately ruled out for the rest of the season.
England had hoped that their key man would return in time to make the plane to Brazil however Walcott has dismissed that.
The 24 year old admits he was offered a chance to get his knee right for the major tournament in June but has turned down the chance, with a long term fix his aspiration.
“It has taken me a while to get the walking right, but it is nearly there.
“At the moment, I am taking it week by week and trying to hit targets. I can’t do much yet.
“I don’t want to be pushing the injury and not be 100 per cent and cause other injuries.
“I was never tempted by any of the offers from people saying they could get me fit for the World Cup.
“I followed the club’s advice. I went to a consultant in London and it was a great decision.”
