The end has come for Penn State football coach Joe Paterno.

The storied collegiate coach has decided to retire at the end of the season, according to multiple reports, wrapping a 46-season tenure that has now been overshadowed by a child sex-abuse case involving a former defensive coordinator.

An announcement is expected later on Wednesday, multiple outlets have reported.

On Tuesday, Penn State's board of trustees announced it will appoint a committee to investigate the scandal that resulted in 40 criminal counts against Jerry Sandusky and led to the athletic director Tim Curley and senior vice president Gary Schultz leaving their posts.

Sandusky, who retired as defensive coordinator in 1999 but still maintained an office, is charged with sexual contact with eight boys over a 15-year period. He has been released on bail.

While Paterno hasn't been linked to the crime and subsequent alleged cover-up -- Paterno fulfilled his legal requirement by bringing allegations of a 2002 sexual encounter, as witnessed by a graduate assistant, to the school's attention -- Pennsylvania state police commissioner Frank Noonan and others in the community questioned whether he should've done more.

The school forbade Paterno from speaking with the media on Tuesday, cancelling his weekly press conference.

"Due to the ongoing legal circumstances centered around the recent allegations and charges, we have determined that today's press conference cannot be held and will not be rescheduled," the school said in a brief statement.
