Ringside Doctor Reveals Why The Mayweather VS McGregor Fight Had To Be Stopped

It was a lot more lethal than fatigue

In case you missed the big fight over the weekend - Floyd Mayweather defeated Conor McGregor via technical knockout. The result was called during the 10th round, when McGregor became "wobbly and floaty".

McGregor was less than impressed by the ref's decision and put it down to fatigue in a post-fight press conference saying: "I would have liked to see the end of the 10th… I have this patch where I must overcome, I get a little wobbly, but it's more fatigue. If you look at the Diaz 2 fight, I came through that."

However, former ringside doctor Darragh O'Carroll, says the referee would have called it due to McGregor showing signs of traumatic brain injury, not fatigue - with a loss of balance being one of the hallmarks signs of concussion.

In a post for Tonic, O'Carroll said: "Fatigue may cause sluggish and slow movements, but does not cause the imbalance and poor coordination exhibited by McGregor in the 10th round."

"Being wobbly, in the setting of pugilistic trauma, will always be treated as the result of head trauma and not as fatigue. To let a fighter continue on would be grossly negligent."

Still, McGregor has just overtaken Ronaldo as the highest paid sportsperson in the world, so maybe all the blows were worth it after all.
