Apparently the World Boxing Commission had some bad information about the health of former heavyweight champion Ken Norton. Boxing News has been informed by boxing manager Butch Gottlieb who is close to the Norton family that Norton did not suffer a heart attack and was in the hospital due to complications from a stroke.
"He had a stroke a couple of months ago and he's been back and forth between the hospital and rehab since," said Gottlieb. "He's now in the hospital because he got an infection while he was in rehab so they had put him in the hospital just to keep an eye on it. He's not in delicate condition. He happens to be strong as a horse....Kenny does not speak real good because the stroke paralyzed part of his face, but he's getting better and they expect him to come out of this with minimal problems."
