UPDATE: Kvitova is out of surgery, and her left hand will be in a cast for at least three months:

Earlier today, BBC Sport's David Ornstein reported Kvitova was undergoing "potentially career-saving surgery," and gave context to the circumstances surrounding the attack:

Below is the original story, posted early Tuesday morning:

Two-time Wimbledon champion Petra Kvitova has been injured in an apparent robbery in her home in Prostejov, Czech Republic. Kvitova's agent confirmed reports of the attack on Tuesday morning.

According to reports, a man was able to gain entry into Kvitova's building on Tuesday morning by posing as a maintenance worker. Kvitova was able to fend off the attack but sustained severe lacerations to her left hand. The assailant has yet to be apprehended.

"Thank you for all your heartwarming messages today," Kvitova said in a statement. "As you may have already heard, today I was attacked in my apartment by an individual with a knife. In my attempt to defend myself I was badly injured on my left hand. I am shaken, but fortunate to be alive. 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. Thank you all again for your love and support and now I would appreciate some privacy while I focus on my recovery."

The official Facebook page of the Czech Fed Cup Team posted a message from Kvitova (translation via Facebook):

"Hello, thank you all for your messages and support. What happened to me, it was certainly not pleasant, but it's behind me. Now for me is the main doctors to find out what's on my arm. I trust them and believe that this goes well, I have the best care and I'm in contact with my loved ones. The worst thing I've done. Thanks again for thinking of me. Don't worry about me! Petra."

Earlier on Monday, Kvitova announced her withdrawal from her first event of the 2017 season at Hopman Cup due to a stress fracture in her right foot. Kvitova, who has been in a walking cast for several weeks, tweeted that an MRI showed the injury was healing but not fast enough to compete in Perth.
