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 for tomorrow's game against the Eagles, then changed into a white sweatsuit and left Giants Stadium in a Jeep about 1:30 p.m.

Police initially said the doctor who treated Burress early last Saturday 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.

The authorities are especially 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 has since been suspended for not reporting the gunshot injury, as required by law.

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

Domenik Hixon, who has started the three games that Burress has missed because of suspension or injury, will start tomorrow.
