The former Penn State assistant football coach was in court with his wife on Thursday for a brief pretrial hearing.
Sandusky's defense attorney Joe Amendola withdrew his attempt to prevent the attorney general's office from using secretly recorded conversations between Sandusky and two of the 10 alleged victims during the trial.
Amendola said that prosecutors have provided him with thousands of pages of material, and that lawyers for two Penn State administrators have notified him that their clients will invoke their right against self-incrimination if called to testify in Sandusky's trial.
Penn State athletic director Tim Curley and former vice president Gary Schultz are awaiting trial on charges they failed to properly report child abuse and lied to a grand jury investigating Sandusky. Amendola wants them to testify about the report they received in 2002 from a graduate assistant who says he saw Sandusky and a young boy, both naked, in a football team shower.
Sandusky faces 52 counts of child sexual abuse. He is confined to home while awaiting his June trial and has repeatedly denied the charges.
