Mike McQueary, the assistant football coach at Penn State and a central character in the sexual assault scandal, will not attend Saturday's game against Nebraska because of multiple threats, the university's athletics Web site stated Thursday night. But  university officials did not specify the nature of the threat.

McQueary says he witnessed the sexual assault of a young boy, in 2002, by Jerry Sandusky, a former defensive coordinator for Penn State. A graduate assistant at the time, McQueary told a grand jury that the assault happened in the shower room of the facility.

According to further testimony, he then informed his father of the incident and spoke to head coach Joe Paterno the next day. The latter alerted Penn State Athletic Director Tim Curley of Sandusky's behavior. Shockingly, however, at no point did any of those informed of the incident tell law enforcement.

On Thursday, the Allentown, Pa., Morning Call quoted an unidentified member of the university's board of trustees as saying the board would ask that McQueary not be allowed on the field for Saturday's game. At the same time, however, he would retain his job. He has been at practice every day this week.

Tom Bradley, Penn State's new interim coach, who took over after Paterno was fired on Wednesday, said at a news conference earlier Thursday that although McQueary would be coaching on Saturday, it would be a game time decision on whether it would be from his customary place on the sidelines or in the coaches' booth upstairs.

Meanwhile, Paterno stayed at home throughout Thursday and, according to NBC News, has hired a criminal attorney from Washington to represent him. The report, however, was denied by his son, Scott, on Twitter.
