The university's police force conducted several "exhaustive" searches of Beaver Stadium and the surrounding area during the morning and found no evidence of risk, according to a statement.
"Out of an abundance of caution we are notifying fans and the public of the threat that was received, so that they can make their own choices about personal safety and their attendance at today's game," said David Gray, a Penn State senior vice president. "Our first obligation is to the safety of the public and, while police and safety officials have given an all-clear for today's game, we wanted to ensure that visitors were aware of this decision."
No details were provided regarding the nature of the potential threat.
The university said that heightened security measures will be in place, as is standard for all football games.
