A British boxer has died after being rushed to hospital moments after he won a contest in Doncaster.
Scott Westgarth, 31, had beaten Dec Spellman on Saturday after ten rounds and the light heavyweight was seen holding his head and visibly wincing during a TV interview shortly afterwards.
He returned back to The Dome in Doncaster before paramedics took him to the Royal Hallamshire Hospital, where he died on Sunday night.
Westgarth's promoter Stefy Bull confirmed the news on social media. He said: "God bless Scott Westgarth.
