Rutgers is apologizing to Penn State for offensive signs and shirts referencing the Jerry Sandusky child sex abuse scandal that some Rutgers fans displayed during a weekend football game.

Rutgers athletic director Julie Hermann apologized in a statement Monday for the "classless display" that she said does not represent the New Jersey school's views or its fan base.

Several photos posted on an official Rutgers football Facebook page showed fans wearing T-shirts that read "Beat Ped State." Hermann says the photos were removed.

There also was a sign that showed what appeared to be stick figures of a man and boy engaged in a sex act, with "Penn State" emblazoned across the top.

Sandusky, a former longtime assistant football coach at Penn State, was convicted of 45 counts of child sexual abuse.
