Rafael Nadal is still unsure about participating in the upcoming 2014 U.S. Open that is scheduled to start on Aug. 25 in New York City.

Nadal, who is still recovering from a wrist injury he sustained during a practice session, said in a recent interview that he is aching to get back in shape to make it into the final Grand Slam event of the year where he is the defending champion and considered to be a strong title favorite.

But while he wants to defend his title at Flushing Meadows, Nadal admitted that he needs to wait until the weekend before making a decision on whether or not to travel to New York.

"My dream is being there and I will work for it," Nadal said via Tennis World USA. "If it has healed I'll have to try and see how I feel when I train and Friday or at latest Saturday a decision will be made. Time is short and we'll have to wait and see if it is enough or not."

Nadal was forced to skip two tune-up events -- Masters 1000 event in in Cincinnati and Toronto -- where he was the defending champion.

"I will propel myself if I will have to," Nadal said. "If I will have to cut the healing time short I will. It all depends on how painful the wrist will be after the cure. We all know that once a muscle isn't trained for a while it takes time to get back to full shape. When I take the bandage off, I will try to hit and see if it will hurt or not."

The 14-time Grand Slam champion underwent several examinations on Tuesday and his doctor, Angel Ruiz Cotorro, said that the results were not bad, but are not good either.

"The images showed what we expected to see. I am neither optimistic nor pessimistic, I'm realistic. Now begins the rehabilitation process and then see on the track," Cotorro said.

Nadal, who has not played since losing to Nick Kyrgios in the fourth round of the 2014 Wimbledon, defeated current world No. 1 Novak Djokovic in last year's final.
