Notre Dame players and staff members are dealing with a "flu or a virus" ahead of Thursday night's College Football Playoff semifinal against Penn State, a school official confirmed in a statement to CBS Sports' Brandon Marcello.

Just four teams remain in pursuit of a college football national championship. It all gets underway later tonight, when Notre Dame takes on Penn State in the Orange Bowl. The winner of that game will face the winner of Friday night’s Cotton Bowl Classic between Texas and Ohio State.

When I made my Sugar Bowl pick, Georgia was the slight favorite, but that flipped by the time the game kicked off Thursday afternoon. The favored Fighting Irish sent home SEC champion Georgia, and I was foolish enough to tell you to put all your chips down on the Bulldogs and their backup quarterback.
