Novak Djokovic has seen his preparations for the French Open hampered by an ankle injury.
He required several minutes of treatment during his match with Grigor Dimitrov at the Madrid Masters after twisting awkwardly during a rally.
Djokovic played on in some discomfort and eventually went on to lose in three sets.
He said: "I didn't prepare myself so well, but, look I'm not trying to find any excuses for the loss. I tried to do my best in this moment, and maybe my best is not like it was in Monte Carlo.
"All the credit also to Dimitrov, because he was the better player on the court. He was striking the ball really well, serving great, changing the pace, and, yeah, he deserved to win, as I said.
"For 12 days after Monte Carlo I haven't touched the racquet. I didn't know up to Saturday if I'm going to come here or not because of the ankle.
"Luckily for me nothing really happened when I twisted the ankle during the match. It was a slight moment. I had good protection on my ankle. So right now the only positive thing that I look into, is that I didn't injure my ankle worse before Rome and Paris."
