Patrick Day has died of head injuries four days after his fight against Charles Conwell in an undercard match. The 27-year-old suffered a brutal knockout defeat in the tenth round after receiving two punches on the chin and fell into coma.
The American super-welterweight was knocked down twice in the fourth and eight round before hitting the canvass in the tenth.
The referee immediately stopped the bout and called for the paramedics team and Day was quickly rushed to the hospital. A brain surgery was conducted on the fighter but promoter Lou DiBella confirmed Day had died on Wednesday, October 16.
