For a short time Saturday night, around 24 hours ahead of today’s 6:29 p.m. EST kickoff, an image celebrating the New York Giants as the champions of Super Bowl XLVI appeared on the team’s website.

Oops.

Doh. (Giants.com / via ESPN) “It is common practice for both teams to create web pages in advance of the conference championship games and Super Bowl,” the NFL said in a statement. “In this case, the hidden URL for the page was inadvertently available for a brief period of time while it was being positioned on the NFL server for possible post tomorrow night.”

Pesky URLs. The headline on giants.com’s main page read “The Giants are Super Bowl champions!” and featured an ad for official championship gear. Good thing Giants Coach Tom Coughlin doesn’t have a problem with bulletin-board material, no matter how accidental.

“I know there have been one or two quotes out there,” Coughlin said. “But to be honest with you, I don’t know that any one of them have been any different than Tom Brady’s [party line].”

Nor was Chris Canty of the Giants deterred. He predicted a final of “Giants 28, NewEngland 17” with a tweet shortly after noon EST.

The Patriots got into the act on Sunday, with a New England sporting good store advertising championship gear.
