DiBella Entertainment has provided an update on junior middleweight contender Patrick Day, who suffered a traumatic brain injury during his bout on Saturday night. He was rushed to Northwestern Memorial hospital where he underwent emergency surgery.

As of Sunday evening, DiBella Ent. indicates that Day is in a coma caused by the injury and is in extremely critical condition.

"On behalf of Patrick's team, we appreciate the outpouring of support, prayers, and offers of assistance from all corners of the boxing community. Updates will be provided as circumstances change. In the meantime, we ask that the privacy of Patrick and his family be respected during this difficult time," DiBella Ent. expressed in a statement.

Day was knocked out cold, in the tenth round, by rising prospect Charles Conwell at the Wintrust Arena in Chicago. The referee quickly waved off the bout when Day hit the mat unconscious.

The bout was streamed by DAZN as part of the Oleksandr Usyk-Chazz Witherspoon undercard.

Day required several minutes of medical attention in the ring. He was fitted with a neck brace and oxygen mask before being taken out of the ring on a stretcher.
