Petra Kvitova is injured in robbery in her apartment

Two-time Wimbledon champion Petra Kvitova says she is “shaken, but fortunate to be alive” after being severely injured by a knife-wielding robber in her apartment Tuesday.

The Czech tennis star suffered damage to the tendons and nerves of her left, playing hand and underwent nearly four hours of surgery.

Czech police told CNN that the attack took place just before 8.30 a.m.

CET in Kvitova’s apartment near the center of Prostejov, a small city about 160 miles east of Prague where a number of Czech tennis pros live and train during the offseason.

“We received a call this morning about an injured 26-year-old woman who suffered injuries to her hand,” a medical emergency spokesman in Prostejov said.

Kvitova, added Spellman, must wear a cast for six to eight weeks and won’t be able to put any weight on the hand for three months.

One of the top players in the women’s game, Kvitova hours before the attack announced her withdrawal from January’s Hopman Cup tournament in Australia due to a stress fracture in her foot.

Kvitova was quick to reassure her fans, also posting a statement on the Facebook page of Czech Federation Cup team a few hours after Tuesday’s incident.

Now it’s (time for) doctors to (attend to) my hand,” wrote Kvitova, who was part of the Czech team which last month won the international event for the third year in a row.
