Patrick Day has passed away aged 27 following his 10th round knockout on Saturday night in Chicago.

Promoter Lou DiBella confirmed Day’s passing on Wednesday “surrounded by his family, close friends and members of his boxing team”.

“He was a son, brother, and good friend to many,” said a statement.

“Pat’s kindness, positivity, and generosity of spirit made a lasting impression with everyone he met.”

Day fought Charles Conwell on the undercard of Oleksandr Usyk’s heavyweight debut.

“Patrick Day didn’t need to box,” the statement from DiBella Entertainment continued. “He came from a good family, he was smart, educated, had good values and had other avenues available to him to earn a living.

“He chose to box, knowing the inherent risks that every fighter faces when he or she walks into a boxing ring. Boxing is what Pat loved to do. It’s how he inspired people and it was something that made him feel alive.”

Conwell, 21, wrote an emotional letter to Day following the fight.

“It becomes very difficult to explain away or justify the dangers of boxing at a time like this,” the statement continued.

“This is not a time where edicts or pronouncements are appropriate, or the answers are readily available. It is, however, a time for a call to action.

“While we don’t have the answers, we certainly know many of the questions, have the means to answer them, and have the opportunity to respond responsibly and accordingly and make boxing safer for all who participate.

“This is a way we can honour the legacy of Pat Day. Many people live much longer than Patrick’s 27 years, wondering if they made a difference or positively affected their world. This was not the case for Patrick Day when he left us.”

Our Thoughts and Prayers go out to the Family and Friends of Patrick Day at this devastating time.
