Judge John M. Cleland's order to delay the start of the trial came as prosecutors filed objections to the retired defensive coordinator's motions to dismiss charges, the Pittsburgh Tribune-Review reported Friday.
Sandusky attorney Joe Amendola filed for a delay last week, arguing the charges against his client were so vague, a defense could not be mounted.
In documents filed Thursday, prosecutors said Sandusky, charged with abusing 10 boys during a 15-year-period, gave up his right to pretrial challenges to the charges when he waived the case to court rather than challenge them in a preliminary hearing.
Cleland will hear pretrial arguments April 5.
Sandusky, 68, of College Township, is under house arrest on $250,000 bond.
