England has made two changes to the team to face South Africa in the World Cup Pool C game on Saturday.
Saracens scrum half Kyran Bracken and Leicester flanker Lewis Moody replace Matt Dawson and Richard Hill respectively in the starting line up. The changes mean Andy Gomarsall (Gloucester) and Joe Worsley (London Wasps) join the replacements.
Dawson and Hill, who both sustained hamstring injuries against Georgia last weekend, are expected to be fit to face Samoa next week. Head Coach Clive Woodward insisted his squad had the strength in depth to cope with the missing pair at the Subiaco Oval.
"I thought everybody was going to be fit on Wednesday but that isn't the case," said Woodward. "Although they were just minor injuries, the two players just weren't quite ready. We've still got a very experienced team. Kyran Bracken's a very experienced player as are Lewis Moody and Joe Worsley. Matt thought he'd be fit but he's just not quite there and I said before we left England that success would come down to using all 30 players.
"Someone else will step up to the plate now. To bring in Kyran and Lewis Moody and having Joe Worsley on the bench doesn't worry me. Kyran's got lots of experience, the last time we played a major nation he was at No.9 and it was a close call between Bracken and Dawson."
The only other England casualty is lock Danny Grewcock who sustained a hairline fracture to his toe and will be given two weeks rest to allow it to heal.
