Andy Murray faces late call over his fitness

The world No 4, who rolled his right ankle during Saturday's third-round win over Michael Berrer, has been undergoing treatment in a bid to be fit for this afternoon's clash, which is scheduled third on Court Suzanne Lenglen, with a likely start time of around 3pm.

The Scot stepped on to the practice courts for a light warm-up late yesterday, but has decided to leave a final decision on his continued participation in the tournament until today.

Should he decide to play, Murray's record against Serbian Troicki is good, with the British No 1 having beaten the 15th seed in each of their previous three encounters.
