Andy Murray will today bid to complete a stunning French Open fightback against Viktor Troicki after coming from two sets and a break down to tie the fourth-round match at 4-6 4-6 6-3 6-2 when play was called off because of darkness.

The world number four's participation looked in doubt because of an ankle injury and he lost the first five games before gradually turning things around.

He lost the second set from a break up and then won the second from a break down before ending the evening very much on top against the 15th seed from Serbia.

All eyes were on Murray's right ankle after he rolled it during the second set of his third-round win over Michael Berrer and finished the match virtually on one leg.

The Scot had declined to give any updates on his condition in the 48 hours between matches but still looked very cautious with his movement in a gentle practice yesterday lunchtime.
