(NBC NEWS) NBC News has learned that former Penn State football assistant Mike McQueary filed a whistleblower lawsuit seeking $4 million from the university on Tuesday afternoon, claiming he was made a “scapegoat” for the university’s failures to rein in a coach accused of sexual assault.

McQueary is the staffer who said he witnessed assistant football coach Jerry Sandusky having sex with a boy in the locker room in 2001, and reported what he saw to head football coach Joe Paterno. Sandusky, 68, was found guilty in 2012 of 45 counts of child sexual abuse.

The lawsuit says McQueary is seeking $4 million. His base salary in 2011 was $140,400 plus bonuses and benefits, making his anticipated earnings over the next 25 years at least $4 million. McQueary says he was placed on administrative leave a week after a grand jury found that university officials made false statements about what McQueary had told them. Gary Schultz, a former senior vice president at Penn State, and Tim Curley, the former athletic coordinator, are accused of lying to a grand jury about what they knew of sex abuse allegations against Sandusky. The university has been paying the legal fees of other Penn State employees in the case, but not McQueary’s.
