Petra Kvitova could be back on a tennis court in six months, her surgeon said on Wednesday.

The two-time Wimbledon champion underwent surgery to repair severe lacerations and damage to her left hand and fingers after she was attacked in her home in Prostejov on Tuesday.

“Surgeon Radek Kebrle said that the operation on Petra’s left hand went very well, with no complications,” Kvitova’s publicist said in a statement.

“Petra will be on bed rest for 14 days, she will begin slow rehabilitation at around 6-8 weeks post operation. If that rehabilitation process goes well, Petra should be able to grip a racket for the first time (but not play tennis) at three months. The best-case scenario is that Petra will be able to return to the tennis court after six months.

“It is too soon to specify when precisely she can return to competition, but Petra is ready to do everything she can to get back competing at the highest level. Petra is happy with how the operation went and is in good spirits.”

Kvitova had ended the season ranked No.11 after a run to a second title of 2016 at the Huajin Securities WTA Elite Trophy Zhuhai.
