NEW YORK (AP) - Bob Costas will host NBC's "Sunday Night Football" pregame show from the site of the game starting this season.

The network announced Wednesday that it was tweaking the format of the show. The reunited tandem of Dan Patrick and Keith Olbermann will remain in the New York studio to provide highlights. They will be joined by two new hires who recently retired from the NFL: former Indianapolis Colts coach Tony Dungy and ex-New England Patriots safety Rodney Harrison.

Costas will share the onsite set with game announcers Al Michaels and Cris Collinsworth.
