Minnesota Vikings vs. Philadelphia Eagles Game-time Changed

The Minnesota Vikings game versus the Philadelphia Eagles on December 26th. has been changed to a Sunday night game.  The kick off will take place at 7:20 CST at Lincoln Financial Field in Philadelphia, PA.  We currently have Vikings vs. Eagles tickets starting at $150/Ticket.  I was surprised to see the game-time change considering that the Vikings record isn't what was expected.  Maybe people want to see Brett Favre in one of his last games?
