Jeff Nippard was allegedly attacked by another bodybuilder while the fitness influencer was working out in the gym.
A viral video has been circulating online, showing fellow muscle man Mike Van Wyck appearing to grab the Instagram star by the neck and throw him to the floor.
Nippard, who has two million followers on Instagram and owns a fitness app called MacroFactor, subsequently took to Instagram to post a picture of himself appearing to be in a hospital, along with a caption addressing the video.
The picture showed that he had sustained a graze on his neck, with Nippard stood next to a CT scanning machine.
During the statement, he clarified to fans that he was 'OK' following the incident.
While it is unclear what caused the incident, Nippard also claimed that rumours that he had 'approached Van Wyck first were false'.
He added: 'I don't know why he attacked me other than that he really, really hates my training style.'
Mail sport has since reached out to Van Wyck's team for comment.
As Nippard suggests, it appears their feud may have stemmed from disagreements over their different training methods.
Recently, IFBB Pro-turned-bodybuilding coach Van Wyck has hit out at science-based trainers on his social media account.
It prompted a response from Nippard, who employs a science-based training regimen, who clapped back at the criticisms of Van Wyck on his YouTube channel.
While Van Wyck had not directly named Nippard in his Instagram video, he had claimed bodybuilders who use science-based training plans are 'mediocre'.
It appears their online feud could have played a part in the events that unfolded in the viral video that was circulating the internet on Tuesday.

In a clip published to his Instagram, Van Wyck had said: 'We all know the science-based guys. Any top three you choose.
'Tell me if you'd describe their physique as excellent, average or mediocre.
'And where would you put [them] in that? I guarantee it's not excellent. Somewhere in the middle, right?'
He added: 'Science guys really need to answer this question before anything: Why is it that you remain so mediocre, yet you know so much?
'Because if I knew a lot of s*** I'd be very well versed in that topic.
'Say I was some financial wizard and I knew how to read the stock market and I can see investments and see what businesses are going to say, I'd be f***ing rich, right?'
'In bodybuilding, you can be this short in some cases,' he would go on to add. 'And you can be an expert on muscle, but you don't have any. If you do have any it's not that well put together.'
'Sadly you do need to apply what you know for people to trust you. But they got these f***ing nerds or dorks trying to prove themselves at shows and they come in last.'

He would refer to another finance reference in the video, likening science-based trainers to those who trade cryptocurrencies like Bitcoin online.
'There's a lot of scammers in the day trading world. Anyone who's a day trader or a bitcoin guy, buying and selling Ethereum, like they're day traders, sitting in front of their [screens] like they're going to guess the trends - those guys are all bulls*** artists. Run from them.
'Those guys are the guys I'm talking about in the fitness world.'
The video had prompted a response from Nippard, who hit back at Van Wyck's claim that 'science-based lifters were mediocre'.
'I know I don't need to respond to this,' Nippard began in the clip posted on YouTube. 'But since he asked, using science-based training I won natural bodybuilding nationals. I earned my pro card on the competitive stage in the World Natural Bodybuilding Federation. I placed second in my first bodybuilding pro show. While doing this I set the Canadian record on the bench press and a provincial record on the squat.
'I currently weigh 180lbs at 5ft 5in tall which is pretty close to my natural limit, given my height and my genetics.
'That's all besides the point, though, because facts are facts. Information is either right or wrong, it doesn't matter who that information is coming from. If the people with the best physiques had the most knowledge, why would CBum (Chris Bumstead) need a coach? He has the best physique on the planet. Who could possibly know more than him?'
Nippard has previously been seen in Pure Muscle Fitness gyms speaking to pro bodybuilders about whether they're interested in hearing advice or insights about science-based training plans. Several of the pros had stated that they would be interested.
'It's obvious that bodybuilding success comes from great genetics and really hard training. And if you want to make it in the IFBB, steroid use. I like science because it gives me more confidence in what actually works and what doesn't because it isolates variables. If you trust a big guy's advice over scientific studies that doesn't bother me, I listen to what big guys have to say too.'
Earlier on Tuesday, Nippard had released a message to his followers on Instagram addressing the video.
'If you've seen the video by now, I want to clarify the incident,' Nippard wrote.
'First, I just want to give an update that I got a CT scan done and I'm okay.
'In case you didn't see it, this is exactly what happened and there were many witnesses.
'Mike Van Wyck jabbed me in the throat twice in the middle of the gym and then shoved my cameraman.
'There is already a lie going around that Mike asked me to stay away from him, and that I didn't listen, and approached him first. This is FALSE and @puremuscleandfitness has security footage to prove it. I think they should release it.'

Nippard went on to thank the fitness community for the outpouring of support he has received.
'I don't know why he attacked me other than that he really, really hates my training style,' he wrote.
'I certainly gave him absolutely no reason to hate me. And even if I did, there's no excuse to physically attack someone over a disagreement.
'My opinion is that it was the result of anger brought on by the clip I posted yesterday responding to his question about science-based training. Pretty wild stuff.'
