Two-time Wimbledon champion Petra Kvitova has been injured in the hand by a knife-wielding attacker at her home in the Czech Republic.
The player's spokesman, Karel Tejkal, said Kvitova suffered a left hand injury in Tuesday's attack and had been treated by doctors.
He said the injuries to Kvitova, who is left-handed, were not life-threatening.
"What happened to me was certainly not pleasant, but it's behind me," Kvitova said in a statement on the Facebook page of the Czech Republic's Fed Cup team.
"The main thing for me now is that the doctors find out what is the condition of my hand. I trust them and believe that everything will end up well.

"I have the best possible care and I'm in touch with my loved ones. The worst is behind me."
It was not immediately clear how the injury could affect the 2011 and 2014 Wimbledon champion's play. Details of her injury were expected to be released later on Tuesday.
Tejkal said the incident, which he described as a burglary, occurred on Tuesday morning in the eastern Czech town of Prostejov.
Prostejov police spokesman Frantisek Korinek said the attacker, a man who is about 35 years old, escaped from the scene and was at large. He said police have launched a manhunt.
In April 1993, Monica Seles was at the height of her success when she was stabbed in the back during a changeover at a tournament in Hamburg. A man reached over a courtside railing and knifed her, leaving an inch-deep slit between her shoulder blades.
Seles returned to the game 27 months later and reached the 1995 US Open final.
In an unrelated move on Tuesday, Kvitova withdrew from the Czech Republic team at next month's Hopman Cup mixed-team tennis tournament because of an earlier foot injury.
