A key Olympic official said that federations governing 23 sports are working on common eligibility standards to implement the International Olympic Committee’s decision to open the games to professionals.

“To avoid confusion, it is essential that the rule be the same for all,” said Primo Nebiolo, who heads the Assn. of Summer Olympic International Federations. “All I can say is that a great majority of our federations is in favor of opening it up to as many possible top stars in each sport.”

Nebiolo, who also is president of the International Amateur Athletics Federation, governing body for world track and field, said the 23 federations will meet in Rome Wednesday and Thursday and hope to have guidelines ready next year.
