The New York Giants website has been caught congratulating the team for winning Super Bowl XLVI, which is to be held tonight.
The team site is understood to have briefly and prematurely displayed the message, in addition to a link to official Super Bowl champion merchandise and a social networking badge, according to the New York Daily News.
Meanwhile, the New England Patriots have pointed the error out on their own website in an attempt provide further motivation for "the Patriots and their fans".
Patriots coach Bill Belichick is well-remembered for reading his team the Philadelphia Eagles' planned parade route prior to their meeting in Super Bowl XXXIX for added motivation.
