He does not have any proof but Collingwood coach Nathan Buckley believes Dane Swan could have been an unwitting victim of a "game" prominent underworld figure Toby Mitchell is playing.

Mitchell, the heavily tattooed former Bandidos bikie, posed for a picture with Swan after approaching the star midfielder at an Italian restaurant in Melbourne on Tuesday.

Swan immediately contacted Magpies officials to let them know about it. Mitchell uploaded the photo to his Instagram account, declaring he was "having lunch with collingwood champ dane swan".

"Swanny was on the front foot and notified the club straight away," Buckley said after Magpies training on Wednesday. "I think he might be getting caught up in a little bit of a game that is being played there. We have no issues with it."
