All Blacks playmaker Dan Carter could be a doubt for Saturday\'s Test match against Wales after injuring his leg in training, according to media reports. The 30-year-old Carter, capped 93 times for New Zealand and Test rugby\'s highest points scorer, pulled up in training on Thursday with \"a leg twinge\", according to the All Blacks camp. An update on Carter\'s status will be given at the captain\'s run at the Millennium Stadium on Friday. The playmaker\'s replacement would likely be understudy Aaron Cruden.
