GLENDALE, Ariz. -- Welcome to University of Phoenix Stadium, where the New England Patriots face the Seattle Seahawks in Super Bowl XLIX (6:30 p.m. ET Sunday).

Weather conditions: It has been rainy for much of the last four days here, and there was a heavy fog outside this morning, which has delayed some flights coming into Phoenix's Sky Harbor Airport. This stadium has a retractable roof, so weather conditions aren't a huge factor. However, the roof has been opened for the game.

A feel for University of Phoenix Stadium: Opened on Aug. 1, 2006, this still has the feel of a sparkling new facility. The normal seating capacity is 63,400 and can be expanded to 72,200. This is where the Arizona Cardinals play their home games, and it is also the site of the annual VIZIO Fiesta Bowl. There are chair-back seats circling the field entirely, with the majority of them "cardinal red" and some others silver. Behind the Seahawks' end zone, the chair-back seats are temporary and on bleachers. A mural with Patriots quarterback Tom Brady and safety Devin McCourty, along with Seahawks quarterback Russell Wilson and safety Earl Thomas, is hanging high above one side of the stadium, above the Patriots' end zone. There is a large NFL logo on the center of the field and two Super Bowl XLIX logos at each 25-yard line.

Seven players to declare inactive: The Patriots have seven players to declare inactive, and those decisions are finalized and announced around 90 minutes before kickoff. Patriots coach Bill Belichick said Friday that everyone on the roster should be ready to play from a health perspective, including starting center Bryan Stork.

Patriots to wear white: The Patriots are in their white jerseys Sunday night. They are 1-1 in Super Bowls in white.

Vinovich gets the call: Referee Bill Vinovich has been assigned his first Super Bowl. He most recently worked the Patriots' victory over the Ravens in the AFC divisional round of the playoffs. ESPN's Kevin Seifert wrote more on Vinovich in the days leading up to the game.

TV broadcast: Sunday night's game is on NBC, with Al Michaels (play-by-play), Cris Collinsworth (analysis) and Michele Tafoya (sideline) on the call.

Opening coin toss: The Patriots have won 14 of 18 opening coin tosses this season. They have deferred each time.

National anthem: Performed by Idina Menzel.

Halftime: Performed by Katy Perry.

Sparkling Super Bowl program: The official Super Bowl program, selling for $20, has a picture of the Lombardi Trophy in the middle of the logos from both teams.
