Champion Novak Djokovic is fearful of whether he'll be fit to play in his quarter-final at the French Open after pulling off another great five-set escape despite a knee injury that required him to take anti-inflammatory pills just to finish the match.
On his return to action after a 3am finish in the previous round, Djokovic had to demonstrate all his astounding resilience once more to outlast Argentine Francisco Cerundolo 6-1 5-7 3-6 7-5 6-3 on Monday.
Hailed by Cerundolo as "really, the toughest guy ever to play tennis", Djokovic admitted he was "maybe three or four points away from losing".
