Rafa said he was struggling with his back in the match against Mayer.

Rafael Nadal is in the 4th round at the French Open, but there is a little question mark.

According to the Spaniard he felt some problems to his back in the second set against Leonardo Mayer  “I felt pain in my back, so I couldn’t serve full power. I really hope is nothing serious. I already had a back injury in Australia, and throughout my career I have been through a lot of injuries, but always came back. I hope this is not the case however“.

As Rafa said, he has already suffered from a nasty back injury that has prevented him from competing in the Australian Open final. If that will happen again, Rafa can say adieu to his French ambitions.
