Here's the pic. Unfortunately, Eric looks exactly like Justin Verlander which makes this kind of awkward.
That's him with the backwards Packers hat (of course) and hands all over the ball and Prince's arm. Here's some other views with a little more of a high resolution pic too.
It's hard to find videos of Major League Baseball games because they're basically communists when it comes to watching videos online, but I was actually able to find the perfect video. I don't think there was fan interference since Prince was reaching into the stands and the fans were reaching over into the field of play. If I was the guy next to Eric in the red jacket, I might call fan interference though, cause not was he all over his arm, but he made the ball bounce directly off the side of his head. Verdict: I'll allow it.
