Junior middleweight Patrick Day, who suffered a brutal 10th-round knockout loss on Saturday night, died from brain injuries on Wednesday at Northwestern Memorial Hospital in Chicago, promoter Lou DiBella said. Day was 27.
Day, of Freeport, New York, was knocked down by right hands in the fourth and eighth rounds by unbeaten Charles Conwell, a 21-year-old blue chip prospect from Cleveland and a 2016 U.S. Olympian, in the scheduled 10-round fight on the Oleksandr Usyk-Chazz Witherspoon undercard at Wintrust Arena.
Although Conwell was clearly winning the fight, Day was competitive in many of the rounds. However, in the 10th round, Conwell landed two rights and a left hook that knocked Day out cold.
