American boxer Day undergoes brain surgery

Day was rushed to Northwestern Memorial Hospital after he was knocked out by his compatriot in the 10th round of a bout on the undercard for Oleksandr Usyk's heavyweight debut against Chazz Witherspoon.

The 27-year-old, who was removed from the ring on a stretcher, is in a coma following emergency surgery.

Day's promoter Lou DiBella tweeted: "Pat Day makes any room he is in a better place. I've never met anyone who's met Patrick and not liked him. Never heard him utter a mean word.
