Jerry Quarry, 45, a heavyweight contender in the 1960s, has applied for a California boxing license, and it is expected that former heavyweight champion Larry Holmes, 40, will soon do the same.
Promoter Paul Konapelsky wants to match the two Aug. 30 in Ontario.
Quarry, who fought heavyweight champions Floyd Patterson, Muhammad Ali and Joe Frazier, has completed his license application and passed the neurological examination required of California boxers. Holmes has not applied.
"Since both of them are over 36, they are both required to appear before the State Athletic Commission to get approval to box here," said Ken Gray, the commission's executive officer.
The next commission meeting will be Aug. 17 in Sacramento.
