Spanish tennis star Rafael Nadal sent shockwaves through the US Open on Sunday when he collapsed during his post-match news conference in New York because of severe cramping in his thigh.
According to the Sydney Morning Herald, Nadal received treatment in the tournament's main interview room, flat on his back behind the desk.
"I just have cramping in my leg in front and behind, that's why I was so painful. I will train normally on Monday," the 25-year-old said later.
"It was just a normal cramp that could have happened anywhere, but it happened in the press room. Anywhere else, nobody would have noticed," he added.
Nadal had spent two hours and 39 minutes under the blazing sun on Arthur Ashe Stadium, while taking down Argentine David Nalbandian 7-6(5), 6-1, 7-5, in the third round.
The defending champion will now play Gilles Muller in the fourth round.
