Harrison, Tyree reunion 4-5 p.m.

I swung by the NBC p.r. office to swipe a slice of pizza earlier, and left with both that and a bit more information regarding Sunday's six-hour pregame extravaganza than what was in the official news release the other day.

For example: One of the expected highlights of the day - a live, on-set reunion of the two principals of Catch 42 from four years ago, Rodney Harrison and David Tyree - is scheduled for the 4 to 5 p.m. hour.

The two have met before, but it has been about three years since they were together.

(Remember, it's a live show, so all scheduled times are subject to change.)

Tony Dungy's sitdown with Tom Coughlin is scheduled for the 1 p.m. hour. Bob Costas interviews Giants president John Mara in the 2 p.m. hour.

Barack Obama chats with Matt Lauer at around 4:30.

Dungy and Victor Cruz revisit his days at Paterson Catholic High School in the 4 p.m. hour, which also will include a seven-minute feature by former Newsday Giants beat writer Peter King on former Saints special teamer Steve Gleason, now battling ALS.

Dan Patrick interviews Eli Manning in the 5 p.m. hour. Good luck with that, DP.
