Matt Damon was still sporting a hint of the 'stache he's not too crazy about yesterday as he headed in for an appearance on The Late Show.

His interview with David Letterman won't air until Friday, but it looks like Matt had a little wardrobe change, since he left the studios in a Saints jersey. The die-hard Patriots fan may soon be in another team's uniform, if he decides to join Ben Affleck playing Yankees in The Trade.
