Nadal fans begin to worry as video surfaces of Spaniard clutching his knee in practice: "French Open main drawn starts in 17 days"

Rafael Nadal's chances at Roland Garros have always been under question but even more now after a video from his practice surfaced online.

Rafael Nadal will play at Roland Garros according to the most fresh information available but a new video of him in practice has cast doubt over those claims. The Spaniard's camp has been really tight-lipped all throughout this process with very little information available. No videos were shown until now and this one looks to have been taken in secrecy as well.

It shows Nadal in obvious discomfort clutching his knee and just looking very winded. His coach Moya was next to him as well as a few other people and none of them looked particularly happy or relaxed. They all had what looked like very tense body language suggesting worry. With the event only weeks away, it doesn't look like Nadal is in really good shape which casts doubt over whether he'll be good to go at Roland Garros.

Check out the video for yourself.
