Vaughan undergoes scan

England's World Cup concerns over Michael Vaughan grew on Monday when the right-hand batsman was sent for a scan on his right calf.

Vaughan scored a half-century in England's Group A win over Pakistan on Saturday in Cape Town but did not field because of the problem.

England play India on Wednesday in Durban in a game that is likely to decide whether Nasser Hussain's team makes it to the Super Six stage.

Vaughan missed a Test series in Pakistan at the end of 2000 with a torn right calf muscle. The right-hander's career has been blighted by a string of injuries.
