Nikolay Davydenko is set to go into business following retirement. The former world No. 3 officially announced his retirement at the Kremlin Cup in Moscow.

Davydenko, who has not played since a French Open first-round loss, said injuries were no longer allowing him to play his best tennis. The four-time Grand Slam semifinalist, who won the 2009 World Tour Finals, was famous for his low profile — in other words, for not being famous — during his career. A match-fixing controversy in 2007 was perhaps his most publicized episode. However, the 33-year-old Russian sees himself as well-known enough to use his name in a new venture.

"I will be doing business, finances. It will be an international business. I am known not only in Russia. For instance, in China as well," said the Russian, who had a Chinese clothing sponsor for much of his career.

Davydenko has a two-year-old daughter with his wife, Irina, who was also a regular presence on tour. A ceremony will be held marking his retirement this week during the Kremlin Cup.
