Actor Rob Riggle, best known for his stint as a Daily Show correspondent, will join Fox NFL Sunday this season as the pregame show's "comedic prognosticator," replacing Frank Caliendo. He will contribute a weekly segment where he challenges the show's analysts -- Terry Bradshaw, Michael Strahan, Jimmy Johnson and Howie Long -- to see who can correctly predict the most games. Riggle, who served oversees in Kosovo and Afghanistan, is current on Adult Swim's NTSF:SD:SUV.
