Longtime New England fan Matt Damon may be sporting a Russell Wilson jersey on TV if the Seahawks win the Super Bowl.

Damon revealed on KIRO Radio’s Tom & Curley Show that he’s made a bet with his assistant, a diehard Seahawks fan who hails from Sammamish, Wash., that will require Damon to wear the Wilson jersey in a high-profile TV appearance.

“On the talk show of his choice, I have to wear a Russell Wilson jersey,” says Damon. “I have to come out and do the whole talk show in a Russell Wilson jersey.”

If the Seahawks lose, it will be his assistant sporting the other team’s colors.

“Colin and I have about a year of work lined up all over the world and he’s got to wear a Tom Brady jersey everywhere we go,” says Damon. “I’m going to take a picture of him every day. We’re going to the Great Wall. I’m just going to start a blog and it’s going to be this miserable Seattle fan wearing a Patriots jersey in seven or eight different countries.”

Last year, Damon said he was pulling for the Seahawks, but this year, especially with this bet on the line, it’s all about the Patriots.

“It’s a pretty solid bet, we’re both really sweating this one,” he says.

As for the outcome of the game, Damon predicts a Patriots win of 35-13. Regardless of that generous point spread, he did say he thinks it will be a great matchup.

“You guys are awesome and so are we. I’m so excited for this Super Bowl. It’s two really great teams.”
