After Fall, Kyrgios Forced to Withdraw from Queen's Club

ATP Queens Club Aegon Championships preview

The Aussie took a fall at 4-all in the first set and after recovering temporarily, he was forced to pull the plug after dropping the first set tiebreaker to Young.

"It just was a sharp pain when I fell", the Australian told reporters. "It's not great at the moment", he said. "I started feeling it when I was walking, when I was landing on my serve".

The 22-year-old now faces a nervous wait to see if the issue will be serious enough to keep him out of Wimbledon, which gets underway on July 3.

"I'm here anyway. I don't really have time to go home or anything".

"Dog and Fox", he said in a reference to one Wimbledon Village's most famous pubs.

Asked if he was optimistic of playing at the All England Club in less than a fortnight, Kyrgios said: "Yeah, of course".

'I would play Wimbledon if I was injured pretty bad anyway.

"Obviously my main goal is to play well at Wimbledon, so I'm going to try and get it better and rehab it and hopefully it settles down. I'm sure I'll live", he said.

Tsonga outplayed his compatriot Adrian Mannarino 6-2 6-2 in the opening match of the traditional Wimbledon warm-up event in his first match since suffering a four-set defeat by little-known Argentine Renzo Olivo at Roland Garros.

Earlier, fifth-seeded Jo-Wilfried Tsonga beat Adrian Mannarino 6-2, 6-2, and sixth-seeded Grigor Dimitrov - the victor of this Wimbledon warmup in 2014 - looked impressive in defeating Ryan Harrison 6-3, 6-1.

"I had the good sense to have a grass court at my house, so I just practice and prepare this grass season, which is a good surface for me".

Fifth seed Tsonga will play Gilles Muller or Nikoloz Basilashvili in the second round.

Grigor Dimitrov made light work of Ryan Harrison 6-3 6-1 and Denis Shapovalov overcame Kyle Edmund 7-6 (7-4) 4-6 6-4, while Tomas Berdych found the going tough against Steve Darcis. The victory was Shapovalov's second ATP win.

The courts at Queen's Club do tend to be greener at this point in the summer, with Andy Murray and Nicolas Mahut both voicing disapproval a year ago after taking tumbles in the first round.
