We all know how dangerous being a professional fighter can be. However this story of 27 year old professional boxer Patrick day who died in the ring after his KO loss on Saturday is super sad.

Day (17-4-1) was knocked down 3 times -- once in the 4th, again in the 8th and finally in the 10th -- by 21-year-old rising star Charles Conwell during Saturday's fight at the Wintrust Arena in Chicago.
