World No. 20 ranked tennis player Nick Kyrgios admits he won't be at his best healthwise at the upcoming Wimbledon. The 22-year-old has been bothered by a hip injury the whole season.

Kyrgios was nearing a full recovery from the injury before reinjuring his hip at the Aegon Championships last week. The Australian slipped on the grass of the Queen's Club during the first set of his opening-round match at the event.

He tried to play afterward but was forced to retire the clash to American Donald Young.

In a need of matches and more preparation on grass before the start of The Championships, Kyrgios decided to play at this week's The Boodles exhibition. It didn't go bad for the world Number 20, capturing two wins in two matches played against Philipp Kohlschreiber, 33, and Viktor Troicki of Serbia.

''It's not great,'' Kyrgios responded, per Tennis Australia, when asked about his hip before revealing on Saturday that his physical health is ''probably (at) 60-65 per cent.''

Kyrgios went on to add The Boodles event served to him ''sort of to see where I was and it's definitely not 100 per cent.''

Trying to give himself a chance

Nick Kyrgios' medical staff has been extra busy as the goal is to get the rising player as ready as possible for Wimbledon.

The Championships starts on Monday, July 3, exactly two weeks after the 22-year-old's slip at the Queen's Club.

Kyrgios revealed he's doing everything he could, which included taking anti-inflammatories, rehabbing the injury for an hour and a half day and getting treatment.

However, the world No. 20 claims he is aware that forcing his hip to heal is not a long-term solution by saying ''it needs time to rest.''

Not willing to back down

Nick Kyrgios remains hopeful that he could still leave his mark on the grass of Wimbledon though he is not in an ideal situation.

Kyrgios prefers grass over any other surface as the green court is a perfect match with his aggressive game-style. The world No. 20 hopes to have his big serve and heavy groundstrokes click at The All England Club.

Should that be the case, the Australian would be a legitimate threat to any player on any given day.

Kyrgios insisted that he obviously still feels ''confident'' on the fastest tennis surface and that he knows he ''can serve well, play aggressive and still be successful.''

However, Kyrgios' fitness remains a concern ahead of his first-round match against French Pierre-Hugues Herbert on Monday at The Championships. The 2014 Wimbledon quarter-finalist confessed that his body is not where he would like it to be.
