I never meant this to happen to you, all I wanted to do was win," wrote Day's American compatriot Conwell, 21.
"If I could take it all back, I would. No-one deserves this to happen to them."
Conwell posted a link to the letter on social media with the hashtag #champpatrickday.

Horrible. For both sides. Conwell has to live with this for the rest of his life, he only went in to win the fight...not take a life.
Fighters risk their lives as I have said before. It's boxing.
