All 8 alleged victims mentioned in the explosive Jerry Sandusky grand jury report will testify against the former Penn State defensive coach at a preliminary hearing next week ... this according to ABC News.
Sandusky's lawyer had previously stated that his legal team had contacted the person who was allegedly raped in the Penn State locker room ... and that person insisted nothing ever happened.
But according to ABC, that person -- and all of the rest -- will say they WERE abused when they take the stand.
The prelim is set to begin on Dec. 13. Jerry is currently facing 40 counts of child sex abuse.
