Former Penn State defensive coordinator Jerry Sandusky is telling NBC that he's innocent of child sex abuse charges that shocked the sports world and resulted in the firing of coach Joe Paterno. In a telephone interview with Bob Costas for NBC News' "Rock Center," airing Monday night, Sandusky also denies accusations that he's a pedophile.

Sandusky, who founded a charity for disadvantaged youth, acknowledges that he showered with some boys after workouts and shouldn't have done so.

Paterno was fired last Wednesday for failing to do enough about a 2002 report alleging that Sandusky raped a young boy in the Penn State football showers.
