World No.2 Rafael Nadal's uncle and former coach Toni Nadal has said that the Spanish tennis great is considering what schedule to maintain during the upcoming season restart on the ATP Tour, even if it means not playing the US Open.

"I have spoken to Rafa and he is doubting which tournaments to play," Toni told ESPN Deportes. Nadal is the defending champion at the US Open and the French Open. Both Grand Slams are set to happen within four weeks of each other with a number of tournaments squeezed in between them.
