Rahul Ravipudi, one of Greener's attorneys, said: "[The judgement] cements a critical legal victory not only for our client, but also for injured athletes across California by reaffirming that sports instructors and facilities may be held accountable when they unreasonably increase risks beyond those inherent in the sport."
BJJ legend Rener Gracie, who was called as an expert witness in the case, said: "The black belt instructor did a technique that placed his entire body weight on Greener's neck, causing him to instantly fall limp and lose all function of his limbs."
It comes after a champion martial artist
Mohit Sharma, 21, was fighting in the second round of a university wushu tournament on Monday in India.
People immediately rushed to provide assistance, and medics were called.
Sharma, though, could not be revived after a reported suspected heart attack.
According to the Indian Express, he was taken to the on-site medical centre then transported to a district hospital.
But the young boxer sadly passed away as he was declared dead on arrival at Kharar Government hospital on Monday evening, it was later confirmed.
Meanwhile, a mixed martial arts fighter died days after collapsing during a training session.

80s rock icon enjoys a cupan tae with Kneecap at Dublin cafe
An 80s rocker has shown his support for Kneecap by joining them for a cup of tea in Dublin. Paul Weller has once again backed the Belfast rap trio Kneecap, having been pictured enjoying a cupan tae with two of the three band members at Phibsborough's Bang Bang Cafe last Thursday night. Last month, Weller was one of 40 acts who signed an open letter opposing what they claimed were efforts to censor the trio, amid an ongoing legal battle for the band. An 80s rocker has shown his support for Kneecap by joining them for a cup of tea in Dublin. Pic: Benjamin Cremel/AFP via Getty Images Móglaí Bap, DJ Próvaí and the band's manager Daniel Lambert were supposedly celebrating with Paul after their Irish language film nabbed the top prize at the Celtic Media Awards. Sharing the snap to Instagram, Bang Bang cafe was inundated with messages of love and support for the musicians. 'As if we don't already love Weller enough,' one user wrote. View this post on Instagram A post shared by Bang Bang (@bangbangd7) 'Not one bit jealous! Paul Weller is just the greatest!,' another penned. Chatting about Paul's trip to Ireland, an insider told The Irish Sun: 'Paul was over in Dublin working on another project but wanted to meet up with Kneecap. 'He's a good friend and Kneecap were able to thank Paul for all his support over a brew.' The meet-up comes after band member Mo Chara was handed a terrorism charge late last month. The rapper, whose real name is Liam Óg ÓhAnnaidh, has been charged after displaying a Hezbollah flag at one of the band's concerts at the O2 Forum in Kentish Town, London, last November. 27-year-old Mo Chara is due to appear at Westminster Magistrates' Court in London on June 18.

Love Island casting comes under fire AGAIN after it's revealed star had TikTok account where he ‘secretly films women'
AXED Love Island hunk Kyle Ashman took part in 'misogynistic' videos with a pal where they secretly filmed women. 3 Kyle was axed from the show earlier this week Credit: Instagram Now it has been revealed that he had a joint TikTok and YouTube page with a friend called Fin Musker. Whilst the joint pages have been wiped of content, a source has told The Sun that the videos involved them 'picking up girls and filming them without knowledge'. The source added that the videos 'displayed misogynistic behaviour towards women'. Some content still online shows Fin and Kyle out on the town, kissing women and speaking to them in bars. READ MORE ON LOVE ISLAND When approached about the videos, Kyle did not wish to comment. It raises further question marks about ITV's vetting process for its reality shows. Earlier this week Kyle was sent packing from Majorca after The Sun alerted show bosses that he had been arrested on suspicion of a machete attack and was only cleared by police last month - meaning he would've been in discussion with authorities whilst auditioning for Love Island. ITV chiefs sent him home from Most read in Love Island A source said: 'All of the online content had been cleared so may not have come up on surface level checks, but for this kind of show far deeper trawls should be in place. 'ITV has steered clear of OnlyFans stars in the past and Kyle's link to one - particularly taking part in joint content of a misogynistic nature - is surely not in keeping with Love Island being a family show.' Love Island's Kyle Ashman reveals he wants show return as Casa Amor hunk after being axed over machete attack on dad ITV declined to comment. Sources said the channel was unaware of the incident and he was not flagged as part of contestant checks. The victim, 38, nearly lost his arm. He was rushed to hospital for emergency treatment and kept in for around two weeks. Another mourner was glassed, one struck with a metal pole, and two people run over by a car during the 15 minutes of terror at a social club. Ashman, who lives in the town, was one of two men to be nicked on suspicion of affray then bailed. Police confirmed that after the matter had been investigated the pair were released with no further action only last month. Speaking after he was axed from the show, he said: "I'm not a bad guy, honestly. I'm a normal guy from a normal place. An opportunity arose to find love and I grabbed it with both hands, and it's been taken away from me. "I've seen the support pages and, who knows, maybe I'll get the chance to go on Casa Amor or as a bombshell, go back in and show you who I really am. Show you I'm not a bad guy. We'll see." 3 He was quizzed by cops over a machete attack that happened in February Credit: Instagram/@kyleashmantr 3 He was released without charge and insists he's a normal guy Credit: Instagram Troubled history of telly hit By Jonathan Kanengoni LOVE Island has been hit by a string of controversies since it first aired in 2015. Malia Arkian lasted just three hours before she was marched out by security in its second year after pushing co-contestant Kady McDermott for spilling wine on her. Sherif Lanre was booted off after nine days in 2019. He had made a vile joke after accidentally kicking fan fave Molly-Mae Hague in the crotch during a play fight. In the same year Women's Aid complained of contestant Joe Garratt's 'abusive' behaviour towards on-screen partner Lucie Donlan. She broke down in tears after he told her to stay away from the other lads. Ollie Williams left after three days in 2020 when he realised he still had feelings for his ex. But his exit came amid mounting pressure on bosses to remove him after pictures of him allegedly trophy hunting came to light. Salesman Haris Namani was dumped in 2023 after The Sun revealed footage of him in a street brawl. The show has also been accused of failing to look after islanders' mental health when filming stops. Sophie Gradon took her own life, aged 32, two years after she appeared on Love Island 2016. And Mike Thalassitis's suicide in 2019, at 26, prompted calls for better after-care by reality shows. In 2022, watchdog Ofcom received 3,600 complaints in a week over alleged misogynistic behaviour by some of the male contestants. And this year it received thousands of complaints about All Stars contestant Elma Pazar's bullying of Ekin- Su Culculoglu during a row.
