Mike McQueary, a key witness in the child sexual abuse allegations against Penn State, has been placed on administrative leave, according to ESPN.

The wide receivers coach was told by school president Rod Erickson on Friday of the indefinite leave.

McQueary has testified in a grand jury investigation that he saw Jerry Sandusky, former defensive coordinator and onetime heir apparent to coach Joe Paterno, sodomizing a boy in the shower in 2002.

McQueary notified then coach Joe Paterno of the incident, but has endured intense scrutiny that he should have notified authorities. On Thursday, McQueary was told he would not be traveling with the team to Nebraska on Saturday after he received multiple threats.

The continuing scandal has already claimed the jobs of former coach Joe Paterno, president Graham Spanier, athletic director Tim Curley, and a vice president Gary Schultz. 

Curley and Schultz have been charged with perjury and failing to report an incident of abuse to authorities.
