Houston, Texas, is the site for Sunday's Super Bowl game, the professional championship for American-style football. Kickoff is set for about 2330 UTC (5:30 p.m. in Houston).
Seventy thousand fans will fill Reliant Stadium, and close to one billion people around the world will watch the National Football League's title game on television.
This is the 38th Super Bowl and the New England Patriots will try to become the 10th team to win two. Their first title came just two years ago.
Quarterback Tom Brady led that victory, and he is back as the signal caller, a big reason why New England is a clear favorite by 7 points, or one touchdown.
But his teammate, defender Rodney Harrison, says he expects a tough battle from the Carolina Panthers, even though they surprised almost everyone by reaching their first Super Bowl.
"Any team that comes and plays for the world championship is going to face a physical game, as guys want to win," he said. "But I think particularly in this situation, I think you have two very physical teams that really, really want the [championship] ring really bad. And whoever hits the hardest and whoever makes the most plays will ultimately walk off as world champion, and deservedly so."
In Super Bowl 38, that will be either the Carolina Panthers or the New England Patriots.
