(Reuters) - American boxer Patrick Day died on Wednesday in Chicago as a result of the traumatic brain injury he suffered during his fight on Saturday, where he was knocked out by Charles Conwell in the 10th round.

Day, 27, had been in a coma for four days following his defeat and, despite having emergency brain surgery at Northwestern Memorial Hospital, doctors were unable to save the junior middleweight.
