Matt Rhule has agreed to a two-year contract extension with Nebraska that takes his contract with the Cornhuskers through 2032, sources confirmed to CBS Sports' Matt Zenitz and Richard Johnson.  Rhule was expected to be one of the leading candidates for the Penn State job -- he played linebacker for the Nittany Lions from 1994-1997 -- but instead he joins Indiana's Curt Cignetti in inking an extension that will take him out of the running for the vacancy in State College.
