Wasps second row Simon Shaw is raring to go after being called into the England squad in place of Danny Grewcock.
Shaw has won 23 caps for England
The Bath lock was forced out of the tournament after breaking his hand against Samoa.
Shaw was unlucky to miss out on the squad in the first place and admitted he was none too pleased when he found out from England boss Clive Woodward.
"This is huge for me as I have missed out on two previous World Cups and thought this was it," said Shaw, who could make the 22-man squad for the quarter-final with Wales on Sunday.
"In 1995 I was first-choice lock and a knee injury robbed me of my chance, but this one was a bitterer pill to swallow.
"It was a huge blow for me at the time as I thought I had done enough to merit selection.
"I kept the conversation brief and there were a couple of four letter words used by me.
"I was moving house at the time and it is just fortunate for those who were on the roads that I don't suffer from road rage as I was driving rather a large truck.
"Now I'm here physically I couldn't be in better shape and mentally I will just have to recapture the state I was in when I played in the warm-up matches."
When Woodward welcomed Shaw into the squad the coach said: "He is a world-class player.
"He did all the pre-season work with us, and he and Graham Rowntree were the unluckiest players not to make the 30-man World Cup squad.
"Simon has been totally involved. He played outstandingly for us against Wales (in August), and he is very close to the squad. We have only been gone a month without him."
Flanker Richard Hill remains England's biggest injury concern as he continues to battle a hamstring problem.
"We won't know finally until tomorrow (Wednesday), but certainly with Iain Balshaw (ankle) he is going to be fine, and Martin Corry (hamstring) is OK," said Woodward.
"So the biggest concern is Richard Hill. This niggling hamstring doesn't seem to go away."
