Cleveland's city council won't further consider a proposal to put Don King's name on the street where the legendary boxing promoter stomped a man to death in 1966.

The honorary "Don King Way" already exists in Cleveland, on a segment of a boulevard near the newspaper he owns. Two council members proposed moving the honorary street name to an avenue where King killed an employee.

King says he's felt contrition for killing the man, Sam Garrett, who he says had jumped on his back. King spent almost four years in prison for the killing and was later pardoned by former Ohio Gov. Jim Rhodes.

IN OTHER NEWS: A boxing expert says the sport shouldn't be used for fundraising or entertainment.

It comes after 49-year-old Neville Knight collapsed and died during an event run by Nabby's Boxing Gym in Hamilton on Saturday night.

Amateur International Boxing Association supervisor Keith Walker says the rules for corporate fighters are too loose.

"They have a medical, and then they just register with Boxing New Zealand."

Mr Walker says there's no age limit or weight or experience restrictions for corporate fighters, unlike other events. He is calling for a crackdown on the rules for corporate fighters.

"A lot of the private boxing gyms in New Zealand are taking these people on, training them and running their own corporate events. That's the part that is getting out of hand now."

Mr Walker says corporate fighters are often mismatched and vary widely in age, weight and experience.

"I certainly do not believe you should be just taking organisations and matching them up with other organisations, or putting people in the ring who are certainly over 40."
