Nadal experiences leg cramp during presser

Rafael Nadal experiences cramps in his right leg and asks for medical treatment in the interview room at the U.S. Open after his third-round win.

Towards the end of his press conference, Nadal leaned back in his chair and after a few seconds asked for the trainer. He then slid down to the floor. Journalists were asked to leave while Nadal received attention from the trainer. The trainer lifted Nadal's legs off the ground and the Spaniard was given water.

At 4:08 pm, Nadal sat up and was talking with the trainer. He described the cramping as "so painful."

Shortly afterward, he resumed his press conference in Spanish and said: "It's just bad luck that it happened in front of the public. It could have happened anywhere. It was hot, I was running a lot and I was sweating a lot...I think I will be fine on Tuesday. I'll try and recover, drink a lot of fluids and go through my normal routine [on Monday]."

Italy's Flavia Pennetta also cramped in her two-and-a-half-hour victory of Shuai Peng on Sunday due to the heat and humidity.
