Petra Kvitova likely to miss most of 2017 season after undergoing hand surgery

Petra Kvitova is likely to miss most of the 2017 season after her surgeon estimated she would not be able to return to the tennis court for at least six months.

The 26-year-old, a two-time Wimbledon champion, suffered serious injuries to her racket-holding left hand in an attack by an intruder at her apartment in the Czech Republic on Tuesday.
