The network said the Monday morning broadcast will include Sandusky's remarks about his former boss Joe Paterno, who died two months after being fired following Sandusky's arrest in 2011.
Sandusky's lawyer Norris Gelman says the interview excerpts are from John Ziegler, a documentary filmmaker working on a defence of Paterno.
In a statement Sunday, Paterno family attorney Wick Sollers says Sandusky had the opportunity to speak under oath during his trial but he "chose not to do so."
Sandusky is serving a 30- to 60-year sentence after being convicted of child sexual abuse. He maintains his innocence and is pursuing appeals.
