It comes after the tennis bad boy withdrew from the Australian Open and announced he will be returning to his mother’s house for knee surgery in the coming two weeks.

The shock decision came just a day before he was due to play his first-round match against Roman Safiullin in the final hammer blow of the tournament.

He was Australia’s biggest shot at a Grand Slam title and originally struggled with an ankle injury that prevented him from playing any of the warm-up tournaments before play began at Melbourne Park.

A routine MRI, performed after Nick developed discomfort in his knee, revealed he has a tear in his lateral meniscus and a cyst, his physical therapist, Will Maher, explained.

He said the injury wasn’t serious enough to be a career threat and it had only become an issue in the past two weeks.

The star said he was shattered to be forced to withdraw from his home grand slam, where many saw him as an opportunity to do even better than at Wimbledon, where he lost the final to Novak Djokovic last year.
