NEW YORK (AP) _ The federal grand jury that has questioned about a dozen major-league baseball players in its investigation of illegal drug trafficking in the Pittsburgh area is expected to hand up indictments Friday, according to a published report.

But the New York Times, in its Wednesday editions, quoted a source familiar with the investigation and said it did not appear that any would be indicted.

A final decision had not been made, however, on whether any of the players would be named as unindicted co-conspirators, the source said.

Several of the players who testified, and perhaps all of them, have been granted immunity from prosecution, although that would not preclude them from being named as unindicted co-conspirators or being named in the grand jury report.

Jerry Johnson, the U.S. Attorney for the Western District of Pennsylvania, has refused to comment on the matter, and has not even confirmed that an investigation is in progress.

Law enforcement officials have previously indicated that drug dealers were the targets of the investigation. The officials have said investigations may be conducted in other cities once the Pittsburgh grand jury is finished. Atlanta and St. Louis have been mentioned as other cities where investigations may occur.

Players who have testified before the grand jury in Pittsburgh are Lee Mazzilli, Rod Scurry and Al Holland of Pittsburgh, Dave Parker of Cincinnati, Dale Berra of the New York Yankees, Jeff Leonard of San Francisco, Enos Cabell of Houston, Tim Raines of Montreal, Keith Hernandez of the New York Mets, Lee Lacy of Baltimore and Lonnie Smith of Kansas City.
