Mike Brown and Brad Barritt injuries add to England's troubles in South Africa England are considering their options over a replacement for Brown, who had only just broken into the team as the starting No 15, displacing Ben Foden, who played on the wing. Brown will be out for six to eight weeks and will require surgery. Bath's Nick Abendanon was last night called up as a replacement for Brown, who expressed his disappointment on Twitter, saying: "I'm broken! Heading bk sometime this week for an op. Brown picked up the injury when Springboks captain Jean de Villiers came clattering through him for his side's second try. "It's very disappointing for Mike," Lancaster said. He's worked hard to get his place in the starting XV. I've told him to remember the quality of the season he's had and to keep in mind that he's got a lot to be proud of this season. Barritt's injury looked alarming, his eye closing immediately after accidental contact. "Brad is very positive and upbeat," Lancaster said. It could have been worse news because it looked bad at the time. Lancaster spent last night working through permutations for the two matches this week. England announce a team today to face the South African Barbarians (South) in Kimberley on Wednesday. He does not want players to overlap if it can be avoided. "We don't really want to have training compromised by having players double up although there are one or two people we want to have a look at," Lancaster said. Although the midweek line-up will primarily feature back-up Test players such as Wasps" young wing, Christian Wade, there will be an opportunity, too, for the likes of seasoned first-teamers James Haskell and Danny Care to show what they have to offer. England arrived in Johannesburg in defiant mood despite the defeat. They have been acclimatising to the difficulties of altitude by training in special chambers in Durban. More than the rarefied air, though, England are well aware that they will have to cope with a more direct assault on the body with the Springboks traditionally even more frenzied in defence of their patch at Ellis Park than at any other venue. Far from being downcast by last Saturday's experience in Durban, even though the scrum was under pressure, hooker Dylan Hartley feels that England have the measure of the Springboks" physical threat. "I think we put down a statement and I would like to think they will have a bit more respect for us next week," Hartley said. We definitely met the physical challenge - that is all I have heard about from them - how physical they are. I am happy that we fronted up. "The lads were saying to each other, 'We'll get them next week," so we have proved to ourselves the game was there for the taking and we can beat these guys. We are going into their lair in Johannesburg and there is not a better place to go and do it. It was the first time in history we have won three [away] games on the bounce in the Six Nations. The biggest one for us was going to France and winning. I can only compare next week to that. There have been no citings from the first Test with the 12-hour window now closed.
