Ring legend Ricky Hatton led the tributes after professional boxer Scott Westgarth died following his fight on Saturday night.
The 31-year-old light-heavyweight was taken ill after returning backstage following his points victory over Dec Spelman at Doncaster Dome.
At different points in the fight, which was at times brutal, both men were knocked down to the canvas.
Westgarth, after being announced as the winner, completed his post-fight interviews before stumbling to the back, where paramedics were called to his aid and he was taken to hospital.
The show, which was supposed to feature a headline fight featuring former footballer Curtis Woodhouse, was cancelled when news of Westgarth’s struggles came to light.
He is understood to have died in Sheffield’s Royal Hallamshire Hospital last night.
