Petra Kvitova is due to leave hospital on Friday following surgery on a hand injury sustained in a knife attack.

The two-time Wimbledon champion will miss at least six months of tennis after Tuesday's assault by an intruder at her home in Prostejov, which injured her racket-holding left hand.

Kvitova, the world number 11, faces a lengthy rehabilitation process but received positive news from her surgeon on Wednesday, who announced that she had a chance of resuming playing after the operation went without complications.

The 26-year-old said that she was "shaken but fortunate to be alive" after the attack and underwent surgery lasting nearly four hours.

In addition, she will be discharged from hospital to spend the Christmas period recuperating with her family, and will speak publicly for the first time since the attack on Friday, at a press conference in Prague.

Kvitova's attacker is still at large and Czech police have asked the public for help.
