Kyrgios retires injured during 1st round at Queens

But Kyrgios, who has also been bothered by shoulder problems in recent months, is still determined to compete at Wimbledon, which gets underway on July 3.

Asked what he would be doing now instead this week, Kyrgios said with a smile: "Dog and Fox".

"I felt pretty much everything I was feeling a month ago".

The 22-year-old was expected to make a strong run at the All England Club, but the injury leaves his participation at the grass-court Grand Slam tournament in jeopardy.

Shapovalov was defaulted from his previous Davis Cup meeting with Edmund in February after lashing a ball into the eye of umpire Arnaud Gabas, but this time prevailed 7-6 (7/4) 4-6 6-4. My main goal is to play well at Wimbledon so I'm going to try and get it better in rehab - hopefully it settles down, I'm sure it will.

Mannarino, ranked 62 in the world, had started brightly, swapping breaks with Tsonga, but once the world number 10 found rhythm in his groundstrokes and his opponent needed a time-out in the first set for treatment to his back, it proved a straightforward win.

Kyrgios beat Rafael Nadal on his way to the Wimbledon quarter-finals three years ago, and lost to eventual champion Andy Murray in the fourth round last year. "Yeah, I'll be playing, for sure", Kyrgios said. "The court is obviously new, pretty slick, especially Centre Court". There's no point in playing on if I'm feeling pain to my hip. "I had to play my best tennis to get over him", Tsonga said.

"It settled down, and then on that fall I just felt sharp pain". I'm sure I'll live'.

"With Wimbledon coming, you can't take any chances".

"He's been playing a few matches on the grass, which I think probably helped him".

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.

Murray opens the defence of his title on Tuesday against fellow Briton Aljaz Bedene.

Sixth seed Grigor Dimitrov is also safely through after he beat Ryan Harrison 6-3 6-1.
