Rafael Nadal and Novak Djokovic stayed on course for a second grand slam final showdown with both notching straight-sets wins in yesterday's third-round action.
But fourth seed Andy Murray, who had been coasting in his match against German Michael Berrer, injured his right ankle.
The 24-year-old Scot took a medical time-out and despite obvious discomfort managed a third straight straight sets win, but there will be serious doubts about his fitness ahead of his fourth round match.
A scan will be crucial in his decision over whether or not to pull out.
