Pigskin Pete Not Allowed On Field For Grey Cup 102

I just saw a tweet from Pigskin Pete (Dan Black) saying he isn't allowed on the field for the Grey Cup between Hamilton and Calgary:

"Just informed I'm not allowed on the field for the #GC102 very upset 10 years and this is what it's all for and not allowed #? #OskeeWeeWee" @pigskin_peteIV

This obviously seems wrong. Pete is an icon and something the CFL should be celebrating.
