After making them wait almost a week, Antonio Pierce talked to investigators yesterday about the accidental shooting of New York Giants teammate Plaxico Burress.

What he said, much like many of the details of that night, remains a mystery.

Authorities provided no details of Pierce's meeting with police detectives and prosecutors at the Manhattan district attorney's office, and his attorney did not immediately return telephone calls left by the Associated Press.

Pierce practiced yesterday, then left Giants Stadium in a Jeep around 1:30 p.m.

Police initially said the doctor who treated Burress after he accidentally shot himself in the right thigh at a Manhattan nightclub was to meet with authorities yesterday, but instead she will do so next week.

Authorities are interested in why neither Pierce, who drove Burress to New York-Presbyterian Hospital/Weill Cornell Medical Center, nor Dr. Josyann Abisaab called police to report the shooting. Abisaab was suspended for not reporting the injury, as required by law.

They also are trying to determine whether Pierce tried to cover up the shooting.

Pierce's attorney Michael Bachner told the AP on Thursday that "he had no idea Plaxico had a weapon." But police say Pierce returned to New Jersey with Burress' gun in the glove compartment of his black Cadillac Escalade, and investigators have impounded the SUV to search it for any blood or gun residue.

Pierce refused to discuss the shooting with reporters on Thursday and was not made available yesterday. *
