Philippoussis Likely to Retire After Another Knee Injury

Mark Philippoussis on Wednesday delivered the shocking news his career is likely at an end after announcing he will require a fourth knee surgery.

"I'm not thinking about a comeback at the moment," said Philippoussis, who has re-injured his right knee. "I'm just going to be thinking about spending time with my family, spending time at home and then assessing things -- you know, where life will lead me and what direction I want to take in life and whether I'll be going again. And I'll be honest. You've got to understand it's more a mental battle getting back from injury after injury."

The 31-year-old Aussie will need 2-3 months to recover from cartilage damage in his right knee.

"I want to have that surgery, and then I just don't want to be getting up sore and going to the gym and battling day after day," Philippoussis said. "That's life. Of course, I'm going to be sad. But sooner or later, you know it's going to end and, if it does, I've had amazing memories and two of the biggest memories without a doubt have been the two Davis Cup wins."
