Novak Djokovic may miss Monte Carlo but should be fit for French Open

A statement on Djokovic's website said : "The world's top player has undergone an MRI examination this morning which revealed no structural damage to the joint capsule and ligaments. A joint structures strain requires therapy and strict rest in the following days. Depending on the recovery, a decision will be made on Nole's participation at the upcoming tournament in Monte Carlo."

Djokovic turned his right ankle early in his four-set victory against Sam Querrey and, despite closing out a 7-5, 6-7, 6-1, 6-0 success he appeared to be struggling when he put weight on that foot. The win sealed Serbia's place in the semi-finals of a competition they won in 2010, a triumph that presaged Djokovic's remarkable 2011 in which he won three of the four grand slam tournaments.

"Obviously it's very strong emotion when you play for your country; I guess that's the biggest reason why I kept playing," Djokovic told the Davis Cup website after beating Querrey. "Injuries are a part of sport and you try to avoid as much as you can as an athlete."
