Sources: JoePa to retire at end of season

Penn State coach Joe Paterno has decided to retire at the end of the season, sources have told ESPN and other news outlets.

The coach is expected to announce he's stepping down later Wednesday. Penn State plays its home finale Saturday against Nebraska.

Paterno has come under heavy criticism since former longtime assistant coach Jerry Sandusky was charged late last week with 40 counts of sexual abuse involving young boys. Although Paterno has been cleared of any legal wrongdoing because he informed his boss, athletic director Tim Curley, of an alleged sexual assault by Sandusky in 2002, many believe the coach didn't go far enough to stop the alleged crimes from happening.

Paterno is in his 46th season as Penn State's coach and has recorded 409 wins, the most in Division I football history. He also holds NCAA records for bowl appearances (37) and bowl victories (24) and led Penn State to two national championships.
