27-year-old junior middleweight, Patrick Day, died Wednesday after suffering brain injuries during a match in Chicago.

Day received a brutal knockout and loss Monday night from heavyweight Charles Conwell. Connell who is undefeated and a 2016 U.S. Olympian knocked Day down in the fourth and eighth rounds. Conwell caught Day with a left hook that caused the back of his head to hit the canvas during the final round.

Day was rendered unconscious and referees stopped the match and requested medical assistance for the boxer. He was taken to Northwestern Memorial Hospital where he suffered a seizure and fell into a coma before emergency brain surgery. He never regained consciousness.

On Wednesday Day was disconnected from life support.

“He was surrounded by his family, close friends and members of his boxing team, including his mentor, friend and trainer Joe Higgins,” promoter Lou DiBella said on his website.

Conwell took to social media with a letter addressed to Day. “I never meant for this to happen to you. All I ever wanted to do was win. If I could take it all back I would no one deserved for this to happen to them.” he wrote.
