After ten gruelling rounds with Chris Eubank Jr, a ringside doctor was summoned to examine the swelling that was protruding from the eyebrow of Nick Blackwell.
Following a short assessment, the referee raised his gloves towards the roof of Wembley Arena and waved off the fight, subsequently confirming Eubank Jr as the new British Middleweight Champion in the process.
Celebrations, however, were soon muted as Blackwell was carried from the ring on a stretcher, having already received oxygen. His swelling now eluded to something more sinister, something that would transpire to be almost fatal.
On that fateful night in late March, 2016, Blackwell not only lost his belt, he also lost his career and so nearly his life.
It would later be learnt that Blackwell had suffered a bleed on the brain and technically died in the ambulance on the way to hospital, his fighting spirit still apparent as he cheated death and survived an induced coma, finally regaining consciousness a week later.
Unsurprisingly, he announced his retirement from professional boxing shortly after, taking advice from doctors to never box again.
In the aftermath, Blackwell astonishingly admitted in an interview with the Telegraph that he believes he sustained the bleed on his brain before the fight with Eubank Jr, attributing his injuries to a sparring session with George Groves.
He said: "If I didn’t spar with George Groves, I believe that I could have been world champion now.
"I walked into a right hand - the hardest I have ever been hit. It left me feeling weird. Light headed. Headaches before the fight.”
Assuming this is true, Blackwell's comments again raise serious questions about the safety of how sparring and testing is conducted in professional boxing.
Whilst Blackwell should undoubtedly hold some responsibility for not coming forward about his injuries, leaving such an important decision to the boxer and trainer who have so much to lose by withdrawing from a fight seems nonsensical.
Over the course of putting together Fight Smart, I have explored the idea of involving a ringside doctor for organised sparring sessions, who if present may well have intervened following that big right hand from Groves and potentially saved Blackwell's career.
Had Blackwell also received an MRI scan shortly before the fight, any potential bleed may well have been identified, which again begs the question as to whether an annual scan is enough to prevent similar scenarios reoccurring.
Unfortunately, this wasn't the last time that Blackwell was to have his life altered by an injury sustained while sparring.
Having obtained his trainer's licence in October Blackwell returned to the gym, and as is so often the case with retired boxers, he found the temptation to get back into the ring too great.
Despite no longer having a license to fight, Blackwell sparred in the presence of a professional trainer, subsequently collapsing as a result of swelling on his brain.
The former Middleweight Champion had to undergo surgery to remove part of his skull, once again miraculously evading death, much to the bemusement of the medical professionals who battled to save his life.
Following an investigation into the incident by the British Boxing Board of Control, both the trainer and Blackwell's opponent had their licenses rightfully withdrawn. And while the spar was condemned as an unprecedented act of stupidity from the individuals involved, it did unveil an unfortunate truth.
Both boxers and trainers buy into a 'never say die' mindset, one where you can overcome physical setbacks if you have a great enough will to win. Such an attitude can prove lethal when you're dealing with serious injuries that aren't so simple to fight through or ignore.
Whilst trainers are undoubtedly experienced, they seem to walk an incredibly slim line between safeguarding their fighters whilst also pushing them to their physical limits.
In Nick Blackwell's case, he was failed not only by himself, but by those who had a duty to protect him and his wellbeing.
For this very reason Fight Smart is not just a project, but a necessary investigation that could well unearth some real flaws in boxing regulations that put fighters at risk every time the training bell rings.
