Unless you're referring to some footage that was not aired during the actual game, no there wasn't. There was no visual evidence showing Patterson with possession of the ball, downed, and touching a 49er. That's why the replay couldn't overturn the call. Again, nobody knows what the NFL said about these decisions as this KFFL blurb is derived from some San Fran journalist's assumptions about what calls the NFL might have admitted were in error.
