The management team behind Scottish boxer Mike Towell, who died on Friday following a televised bout, has said it was not aware of any headache complaints by the fighter before the match.
It comes after Towell's heartbroken partner, Chloe Ross, claimed he had been "complaining of headaches for the last few weeks".
The 25-year-old welterweight had to be stretchered from the ring after a fifth-round loss to Dale Evans in a St Andrews Sporting Club fight in Glasgow on Thursday night.
The young father, from Dundee, was rushed to Queen Elizabeth University Hospital where he was diagnosed with severe bleeding and swelling to his brain.
Ross said she was "absolutely heartbroken" to announce that he passed away peacefully shortly after 11pm on Friday evening, 12 hours after he was taken off life support.
In an emotional Facebook post, she said it had been "the longest 24 hours of our lives".
She wrote: "I'm absolutely heartbroken to say my annoying best friend passed away tonight at 11.02 very peacefully.
"Michael had severe bleeding and swelling to his brain. He had been complaining of headaches for the last few weeks but we put it down to migraines with the stress of his fight.
"It has been the longest 24 hours of our lives. My baby has lost his daddy. But he will be so so proud of his dad in what he achieved."
The couple had been together for more than eight years and had a young son, Rocco.

Greg Menzies, head coach at Dundee Boxing Club, said Towell would be sadly missed.
He told the Press Association: "We're obviously devastated for him and his family. It's a small community so everybody's really shocked.
"He was a really nice guy, always winding up people in a good way.
"He was a really good guy and he'll be certainly missed. A lot of guys in our gym are gutted, as even though he was maybe from another club, he was still a Dundee guy and he trained at every gym and he got on with everybody.
"He was one of Dundee's top boxers so he was an inspiration for the young kids. We're all gutted."
Boxing veteran Ricky Hatton MBE has set up a JustGiving fund to raise £20,000 for Towell's family.
On the page, which generated almost £7,000 within an hour, he wrote: "Mike Towell lost his life doing either what he loved or looking after his family - or both.
"A young boy and partner are left behind let's make sure they are looked after."
