Boxer Maxim Dadashev Dies

Actually, you could say he was killed. "Dies" sounds so passive.

They didn't stop the fight until the 11th round.

Brutal.

I looked for more footage, but so far this is it.

At ESPN, "Boxer Dadashev dies from Friday fight injuries":

Dadashev (13-1, 11 KOs), from Saint Petersburg, Russia, and based in Oxnard, California, needed help leaving the ring. He collapsed before making it to the dressing room and began vomiting. He was taken from the arena on a stretcher and was transported by ambulance to the hospital, where he underwent emergency brain surgery for two hours for a subdural hematoma (bleeding on the brain). Doctors hoped to relieve pressure on the right side of his brain, where most of the damage was, with the surgery and placed him in a medically induced coma to allow time for brain swelling to subside.
