Two-time Wimbledon champion Petra Kvitova has been injured by a knife-wielding attacker at her home.

The player’s spokesman, Karel Tejkal, says Kvitova suffered a left hand injury and has been treated by doctors.

Tejkal says the incident, which he described as a burglary, occurred Tuesday morning in the eastern Czech town of Prostejov. He says Kvitova’s injuries were not life-threatening.

Earlier on Tuesday, Kvitova withdrew from the Czech Republic team at next month’s Hopman Cup mixed-team tennis tournament in Perth because of an pre-existing foot injury.
