Previously: CHICAGO — Junior middleweight Patrick Day is in the intensive care unit at a local hospital after being knocked unconscious and suffering a subsequent seizure as he was getting wheeled into an ambulance after a 10th-round knockout defeat to Charles Conwell on the Oleksandr Usyk-Chazz Witherspoon undercard Saturday night.

A source close to the Day family confirmed to DAZN News that Day underwent emergency brain surgery at Northwestern Memorial Hospital. The same source said that Day was given a breathing tube and is in a medically induced coma. 

After sending Day to the canvas two times earlier in the fight, Conwell threw a right hand to the back of Day's ear followed by a left hook. When Day went down, his head bounced off the mat.

Day was unconscious the moment he hit the canvas. Medical staff immediately rushed to the ring and put the 27-year-old onto a gurney and into the waiting ambulance.
