South Africa\'s World Cup-winning coach Jake White on Friday ruled himself out of contention for the England job, a day after indicating he was considering the position. White, the head coach of the ACT Brumbies, said on Twitter he had opted to remain with the Australian Super 15 franchise, where he is in the first year of a four-year contract. \"Always hard turning down a chance to win a world cup, but rugby is about making the right decisions and that\'s to stay with BrumbiesRugby,\" White said. White\'s decision is a blow to the Rugby Football Union, who are scouring the globe for a heavyweight coach capable of guiding England in the build-up to the 2015 World Cup on home soil. The latest development makes it likely that the RFU will be left with a straight choice between England\'s interim coach Stuart Lancaster and another former South Africa coach Nick Mallett. The RFU are keen to confirm an appointment before the end of the Six Nations, with Lancaster looking to enhance his credentials with solid performances in England\'s remaining games against France and Ireland.
