Kvitova attacked by knife-wielding intruder

TENNIS: Two-time Wimbledon champion Petra Kvitova says she is lucky to be alive after being attacked at her home in the Czech Republic.

The 26-year-old underwent almost four hours of surgery after the confrontation with the knife-wielding intruder.

Kvitova suffered damage to the tendons in her left playing hand, along with injuries to all five fingers and two nerves, and will wear a cast for six to eight weeks.

The current world No.11 will miss the Australian Open and a significant part of the season as she won't be able to fully train for at least three months.

"In my attempt to defend myself, I was badly injured on my left hand. I am shaken, but fortunate to be alive,” Kvitova wrote on Twitter.

"The injury is severe and I will need to see specialists, but if you know anything about me I am strong and I will fight this.”

In an earlier statement on the Facebook page of the Czech Republic's Fed Cup team, Kvitova said: "What happened to me was certainly not pleasant, but it's behind me. I have the best possible care and I'm in touch with my loved ones. The worst is behind me.”

Her publicist Karel Tejkal later said the surgery "went well”.

"The injury is serious, but the surgeon says Petra is young and healthy and there is no reason why she can't resume tennis,” Tejkal told AFP.
