"Boxer Patrick Day dies of brain injuries four days after knockout"

Junior middleweight Patrick Day, who suffered a 10th-round knockout loss Saturday night, died from brain injuries Wednesday at Northwestern Memorial Hospital in Chicago, promoter Lou DiBella said. Day was 27. Day was knocked down by right hands in the fourth and eighth rounds by unbeaten Charles Conwell, a 2016 U.S. Olympian, during 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 out Day. When Day went down, the back of his head slammed onto the canvas, and referee Celestino Ruiz immediately stopped the bout without a count at 1 minute, 46 seconds. Day was immediately surrounded by medical personnel and within minutes was taken out of the ring on a stretcher and to an ambulance. He never regained consciousness.
