Former French Open and US Open semi-finalist Nikolay Davydenko has confirmed his retirement from the game.
Former world No 3 Davydenko has not played on the ATP circuit since Roland Garros in May and made his announcement on the sidelines of the Kremlin Cup tournament in Moscow on Thursday.
The 33-year-old Russian revealed that a series of injuries in recent years prompted him to announce his retirement.
The time has come. I have my whole life to live and I officially announce my retirement from professional tennis.
Speaking at a press conference in Moscow, Davudenko said: "I'm 33 years old. Unfortunately, for some years now, I have been struggling with injuries.
"It's hard for me to talk about it. I have been thinking when to announce it.
"The time has come. I have my whole life to live and I officially announce my retirement from professional tennis."
Davydenko won 21 tour titles and the 2009 ATP finals, but never managed to reach the final of a grand slam tournament despite being a four-time semi-finalist.
His greatest achievement was winning the year-end Tour championships in 2009 at London's O2 when he surprised second-seeded Rafael Nadal and world No 1 Roger Federer before beating Juan Martin del Potro in the final.
He was investigated over match-fixing claims in 2007 by the ATP but cleared the following year.
