Argentina's Juan Martin del Potro on Wednesday thanked his fans for the outpouring of support he has received since reinjuring his left wrist at this week's Dubai Duty Free Tennis Championships.

"First of all I want to thank you for the support that is coming from all over the world," Del Potro, who retired Tuesday from his first-round match at that hard-court event, said in a message to his fans on his Facebook page.

"Of course, it is a sad moment for me. This is not what I planned when I was doing the tough preseason training in December, when I dreamed about having the chance of getting closer to the top players. However, it is not the first obstacle I find during my career. If I have learnt something, it's to get up after I fall," the world No. 5 said.

The six-foot, six-inch "Tower of Tandil" acknowledged that his left wrist has worried him for two years, "with ups and downs, but always with the support of my team, my family, my friends and of course you, who stood always there during good and bad times."

"Despite this wrist issue and missing Roland Garros (in 2013) because of illness, I did pretty well and could equal my career-high singles ranking (of No. 4)," Delpo wrote, referring to his comeback after missing most of the 2010 season with an injury to his other wrist.

The 25-year-old Argentine star said he has "full confidence" in his doctor, Richard Berger, who performed successful surgery on his right wrist when he injured it just months after winning the 2009 U.S. Open.

"I will follow his advice and will do the rehabilitation exercises he suggested, and then we will evaluate the steps to follow. Again, thanks for the support! I promise to keep fighting as I always did," Del Potro said without indicating whether he will have to undergo a second wrist surgery. EFE
