PHILADELPHIA (Reuters) - Pennsylvania Governor Tom Corbett said on Tuesday he will file a federal lawsuit against the NCAA over sanctions it levied against Pennsylvania State University in the wake of the Jerry Sandusky child sex-abuse scandal.

Corbett is scheduled to hold a news conference early on Wednesday at the Nittany Lion Inn on the Penn State campus to reveal the details of the lawsuit against the governing body of U.S. collegiate sports, his office said.

In July, the NCAA fined Penn State University $60 million and voided its football victories for the past 14 seasons in an unprecedented rebuke for the school's failure to stop assistant coach Sandusky's sexual abuse of children.

The university recently made the first payment of $12 million, destined for a national fund to support the victims of child abuse. Other sanctions included a ban on the Penn State football team from appearing in bowl games for four years.

The NCAA could not be reached on Tuesday for comment on the anticipated law suit.

The Sandusky scandal was revealed by a state grand jury convened in 2009 by Corbett, then Pennsylvania's attorney general. Sandusky is now serving 30 to 60 years in prison on 48 charges that he sexually abused 10 youths over more than a decade.

Attorney General-elect Kathleen Kane has vowed to probe Corbett's handling of the Penn State case. She has told reporters that she believes that by convening a grand jury in the case that he failed to protect children by delaying prosecution for more than two years.

Corbett, a Republican, has said he welcomes an investigation into how he handled the case.
