Former world number one Martina Hingis retires from professional tennis for the second time in her career due to a string of injuries and health-related problems. However, the shocking fact that she is accused for testing positive for cocaine will most certainly make her miss the sport less.

"The fact is that it is more and more difficult for me, physically, to keep playing at the top of the game. And frankly, accusations such as these don’t exactly provide me with motivation to even make another attempt to do so," said the 27-year-old Hingis. Read more »

Former world number one Martina Hingis has called an early end to her 2007 season after failing to recover from a hip injury. The season has been predominantly unsatisfactory for the five-time singles Grand Slam champion; she won only one title, the Toray Pan Pacific Open in February.

The Swiss tennis star was hoping to be able to compete in the next week’s Zurich Open, but unfortunately, she was forced to pull out because of the injury.

"I'm very disappointed that I have to withdraw from the Zurich Open," Hingis said.

"I've done everything I can to be able to compete, but since Key Biscayne I've had problems with my hip which are stopping me from playing any more tournaments this year and even from practicing properly."

Hingis’ statement that she’ll take "as much time as it needs to get fully fit again" has led to speculation in the Swiss media that she may be about to retire again. (via ESPN)

Before flying back home, Martina Hingis attended the BCBG – Max Azria 2008 spring/summer show. The Swiss tennis star was photographed with singer Natasha Bedingfield and Nigel Barker from 'America's Next Top Model'.

I can’t believe it! Just when I thought that Hingis was the driving-force of Stepanek’s fantastic form and spectacular results (the Czech plays better than ever, as if he’s in top 10!), I hear that they have broken off their engagement. What a disappointment!

"Radek asked me to pass on a message announcing that he and Martina Hingis have split up, they will remain good friends," a spokesman for the ATP said on Saturday.
