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

The 27-year-old Day had been in a coma for four days following the defeat and despite having emergency brain surgery at Northwestern Memorial Hospital, doctors were unable to save him.

“Patrick Day passed away today, October 16, 2019, succumbing to the traumatic brain injury he suffered in his fight this past Saturday, October 12 at the Wintrust Arena in Chicago, IL,” his promoter, Lou DiBella said in a statement

The statement added: “He was surrounded by his family, close friends and members of his boxing team, including his mentor, friend and trainer, Joe Higgins.

“On behalf of Patrick’s family, team, and those closest to him, we are grateful for the prayers, expressions of support and outpouring of love for Pat that have been so obvious since his injury.

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

“Rest in peace and power, Pat, with the angels.”

Day was rushed to the hospital on a stretcher after Conwell landed a flurry of punches which left him motionless on the canvas.

Before turning professional in 2013, Day was a highly decorated amateur who won two national titles.

A world-rated super welterweight contender, Day captured the WBC Continental Americas Championship in 2017 and the IBF Intercontinental Championship in 2019. In June this year, he was rated in the top-10 by both the WBC and IBF.

Day’s death comes after 23-year-old Argentine super lightweight, Hugo Santillan died in July from injuries suffered in the ring and 28-year-old Russian Maxim Dadashev passed away two days earlier from brain injuries sustained during a fight.
