It only emerged on Tuesday night that the 27-year-old was required in the ACT Magistrates Court on August 2 over an assault allegation involving ex-girlfriend Chiara Passari.

The legal issue is just one of many challenges in the personal life of Kyrgios, who is also missing the support of his mother Nill, who's been conspicuous by her absence from the stands at SW19.

Kyrgios' father Giorgos, sister Halimah and girlfriend Costeen Hatzi have been pictured cheering on the 27-year-old from Kyrgios' player box at the All England Club.

However, his mother Nill - a self-proclaimed nervous observer at the best of times - has remained behind at the family home in Canberra.

Speaking to the Sydney Morning Herald, Kyrgios' mum said she watched fellow Aussie Alex de Minaur take a two-sets-to-love lead in his fourth round match, before turning off the TV before her son's thrilling five-set win on Monday night.

“I haven’t watched him play for a while, actually," Nill Kyrgios said.

"I can’t expose myself to that anxiety. I go into a really strange panic. Over the years, I’ve been through a lot.

“It actually got to a stage where I sought help. I was seeing a psychologist for six months. I was not in a good place. My anxiety level watching Nick was so high.”

Nill says she couldn't even bring herself to check the score during her son's match and was waiting by her phone for an update after his epic fourth round win.

Nick Kyrgios' mum in long health battle

Kyrgios' mum has been going through a health battle for the last couple of years and admitted to the SMH that her "kidneys are reaching very close to the end of their life".

Kyrgios spoke last year about the personal toll of travelling around the world and the heartache of being away from his family and his mother.

"My mum is not doing too well with her health," he said at the time. "I'd like to go back and see her."

Kyrgios revealed during the 2021 Australian Open that his mother is "incredibly sick", without going into details.

Nill says she has booked to get a kidney from her husband and hopes that it will be compatible.

While Kyrgios and his family are torn about leaving her behind in Australia, Nill insists that she'll "be ok".

As if he doesn't already have enough distractions at Wimbledon, Kyrgios is also battling a worrying shoulder injury after pounding down 103 aces and needing 16 sets in a gruelling campaign.

He needed painkillers and two medical time-outs to have his serving shoulder massaged during Monday's five-set fourth-round win over American Brandon Nakashima.

But the enigmatic Canberran was pledging to soldier on, knowing he's never been presented with a better chance to land a major having opened up his draw with a drama-charged third-round victory over fourth seed Stefanos Tsitsipas.

"I woke up after Tsitsipas and had some shoulder pain," Kyrgios said.

"I've played so much tennis in the last month and a half, so I almost knew that it was time for my body to start feeling some niggles.

"I think that's normal. At this time in the event I don't think anyone is feeling 100 per cent.

"Obviously Rafa (Nadal), you see him dealing with something niggling all the time. I just don't think there's anyone feeling 100 per cent.

"It's just something I manage. Mentally I feel like I just deal with these things a lot better now."

Kyrgios conceded he never felt 100 per cent physically against Nakashima.

"But mentally I stayed quite calm, knowing I wasn't able to serve full out for the whole five sets," he said.

"Obviously I had to take painkillers, I wasn't returning well for a period of time, then I just stuck to my guns in the fifth set.

"I felt like the level in the fifth set for me was raised whereas his level kind of went away a little bit."
