They are the first men to allege abuse before the 1990s and if are found to be credible, would jeopardize Sandusky's defense argument that a person doesn't become a pedophile in his 50s.
If the accusations by the men are found to be true, Sandusky would have been in his 20s or 30s at around the time the alleged abuse took place.
In June, Sandusky was found guilty of 45 counts of child sex abuse against 10 victims. During jury deliberations, more potential victims stepped forward. Some were speaking out for the first time in public, including Sandusky's adopted son.
The Patriot cited sources that said police were told about the three men who recently came forward.
The grand jury investigation in Sandusky's case is ongoing but it is unknown whether more chargers will be filed. The 68-year-old former Penn State assistant coach, who will likely be sentenced in September, could face over 440 years behind bars.
Meanwhile, fallout is continuing over the findings of former FBI Director Louis Freeh's report on how Penn State handled the Sandusky situation. Freeh's investigation concluded that four high-ranking Penn state officials, including late coach Joe Paterno, covered up child sex abuse allegations against Sandusky to avoid bad publicity.
Paterno's family has rejected the claims in the report, saying they "vehemently disagree" with Freeh's conclusions.
