Swedish boxer Erik Skoglund is in a “serious yet stable condition” after having surgery for a bleed on the brain, his promoters have said.
The 26-year-old is in a medically induced coma and Sauerland Promotion said: “The next three to four days are critical for his recovery.”
Skoglund, who has won 26 of his 27 fights, was taken to hospital on Friday after feeling ill following a training session in his hometown of Nykoping.
His last fight was on 16 September.
That was a defeat by Britain’s Callum Smith in the World Boxing Super Series quarter-final in Liverpool, his only loss to date.
He was due to fight Rocky Fielding on the now postponed Tony Bellew-David Haye undercard.
“Doctors are pleased with the results and Erik remains in a serious yet stable condition,” Sauerland said.
